SUMMARY:Allen SCHEIE (ORNL\, USA)
DESCRIPTION:Quantum dynamics and emergent unconventional phase in Yb2Ti2O7\nRésumé : \nYb2Ti2O7 is a classic and well-studied pyrochlore magnet\, but it continues to hold surprises for science. In this talk I present inelastic neutron scattering showing the low-field evolution of the spectrum from diffuse continua to sharp excitations. I compare this to several theoretical models which capture its behavior to varying degrees\, but which fail in the zero-field phase–which our exact diagonalization calculations show to be an emergent quantum disordered phase between ferromagnetism and antiferromagnetism. Much of the behavior matches the phenomenology of quantum criticality: dimensional reduction\, flat bands collapsing to zero frequency\, and an emergent quantum phase on the boundary between competing phases. Thus although Yb2Ti2O7 is not a quantum spin ice\, it appears to be dominated by intrinsic\, emergent non-magnon fluctuations from an unconventional quantum phase. \n_ \nContact : andrew.fefferman@neel.cnrs.fr \n  \n

SUMMARY:Elizabeth TILLY (University of New Mexico)
DESCRIPTION:Directional Detection as a Tool for Rare-Event Searches\nRésumé : \nMeasuring the initial scattering angle of a particle track provides powerful discrimination in rare-event searches and can enhance detector characterization. The Migdal effect–characterized by a nuclear recoil and an electron recoil originating from the same vertex–is an inherently directional signal. In this talk\, I will present my work with the Migdal In Galactic Dark mAtter expLoration (MIGDAL) experiment which uses a GEM-based TPC. I will discuss the development of our 3D track reconstruction algorithms and studies exploiting its angular resolution to characterize detector response. I will also discuss measurements of drift properties in negative ion drift gas mixtures\, maximizing noble gas components with the aim of improving spatial resolution for MIGDAL Phase II. Together these demonstrate the power and versatility of precise directional track reconstruction for next-generation rare-event searches. \n— \nHanno Filter (College 3 Secretary) \nExternal visitors may ask for a site access to tellier@ill.fr

SUMMARY:Maxime LUCAS (CY Cergy Paris Université)
DESCRIPTION:Non-collinear magnetism in monolayer and magic-angle twisted bilayer graphene\nRésumé : \nRecent studies of twisted bilayer graphene (or other 2D materials) have been stimulated by the discovery of correlations between electronic flatband states due to a moiré pattern [1]. It is shown experimentally and theoretically that the filling of the flat bands affects their correlation and magnetic properties significantly.\nOn the other hand\, the effect of doping on a simple graphene layer is still unclear. Indeed\, its half-filled case is well known [2]\, but unlike other lattices [3] its magnetic properties beyond half filling are mostly unexplored\, except at 1/4 doping [4] i.e when the Fermi energy is set inside of a Van Hove singularity associated to a flatband.\nIn this talk\, I will first present our analysis of graphene magnetism using a combination of the Hubbard model and Hartree-Fock Mean Field Theory (MFT). We work at density values around 1/4 doping (average number of electrons per site Ne=0.75) as it puts the system right into one of the Van Hove singularities found in graphene’s density of states\, giving rise to interesting magnetic properties. We present an interaction-density phase diagram and its associated magnetic orders\, described by their band structure and spin structure factor [5].\nI will then talk about magic-angle twisted bilayer graphene\, to which we applied the same MFT method. While still a work in progress\, I will present the current results we obtained on a Moiré lattice for various values of interaction and flat-band filling\, revealing exotic spin textures such as an antiferromagnetic triangular order on the Moiré scale.\n[1] Y.

SUMMARY:Yukiko TAKAHASHI (NIMS\, Japan)
DESCRIPTION:Material development for HAMR and its prospects\nRésumé : \n\n\nWith the rapid expansion of IoT and digital transformation\, data centers demand ever-higher storage densities. Heat-assisted magnetic recording (HAMR) employs L1₀-FePt\, whose magnetic anisotropy is an order of magnitude larger than that of conventional CoCrPt\, enabling ultrahigh-density recording. Achieving areal densities beyond 4 Tbit/in² requires granular films with grain sizes ~4.3 nm and narrow inter-grain pitch with ~1 nm [1]. However\, conventional segregant systems such as FePt-C and FePt-BN have not yet simultaneously satisfied the required microstructural and magnetic criteria.\n​​ To overcome this limitation\, we introduced a data- driven materials design framework using the NIMS Research Data Express (RDE) platform. By collecting experimental datasets and applying machine learning to FePt-C and FePt-BN systems\, we predicted sputtering conditions that led to FePt-BN-C granular films with sub-6 nm grain sizes and coercivities up to 3.7 T. Although iterative prediction cycles improved the microstructure to 4.9 nm grains\, the results also clarified the intrinsic difficulty of meeting all 4 Tbit/in² requirements within this materials system alone.\n​​Beyond materials optimization\, three-dimensional magnetic recording offers an additional pathway toward higher areal density. As a proof of concept\, FePt-C/Ru-C/FePt-C trilayers were fabricated\, demonstrating epitaxial stacking and distinct magnetic switching behaviors arising from different ordering states in the upper and lower FePt layers [2]. Strategies to improve the structural and magnetic quality of the upper layer will be discussed.\n​​\n​​ [1] D. Weller et al.\, IEEE Trans. Magn. 50\, 3100108 (2014).\n​​ [2] P.

SUMMARY:Uri VOOL (Max Planck Institute for Chemical Physics of Solids)
DESCRIPTION:Hybrid circuits with van-der-Waals superconductors\nRésumé : \nSuperconducting circuits (SCs) are quantum devices that mimic the behavior of atomic systems even though they are made up of macroscopic microwave circuit elements. Their tunability\, high coherence\, and strong coupling has led to their rapid development as a leading implementation of quantum hardware. Traditional SCs are made using known superconductors such as aluminum or niobium\, but the integration of novel superconductors as part of the circuit can lead to new scientific insights and new capabilities. Such hybrid circuits are ideal sensors\, capable of measuring the superconducting gap structures of novel materials using micron-sized samples\, which is especially useful for interface superconductors or van-der-Waals flakes which cannot be probed with bulk techniques. Furthermore\, the unique quantum properties of unconventional superconductors can be utilized to make a new class of quantum devices. This talk will present recent results where we explore van-der-Waals superconductors in cuprate and kagome systems with hybrid circuits\, and a path towards utilizing them in new hybrid devices for quantum technology. \n_ \nContact : equipe-seminaires-nano@listes.grenoble.cnrs.fr

SUMMARY:Young Keun KIM (Department of Materials Science and Engineering\, Korea University)
DESCRIPTION:3D Chiral Spintronics: Spin-Selective Transport through Chiral Magnetic Nanohelices\nRésumé : \n\n\nChiral crystals with well-defined handedness in atomic arrangements exhibit intriguing properties such as spin selectivity\, asymmetric magnetoresistance\, and skyrmions. Although similar geometry-induced phenomena have been observed in chiral organic-molecule-based systems\, synthesizing uniform inorganic nanostructures with desired chirality using a scalable method remains challenging. We electrochemically synthesized 3D chiral ferromagnetic cobalt-iron nanohelices from nanoparticles in anodized aluminum oxide templates. The spiral directions and the number of strands were regulated by incorporating chiral molecules and applying an appropriate potential. We demonstrate the observation of Faraday’s law of induction at the nanoscale and how chiral nanohelices regulate the direction of electron flow. The implications of our findings extend to the technological realm\, particularly in the context of charity and ferromagnetism-based spin-tunable devices.\nReference :\nY. S.

SUMMARY:Thomas BRUN (IRIG / Spintec)
DESCRIPTION:MAROT : Un magnétomètre miniature pour l’exploration spatiale\nRésumé : \nCette thèse porte sur la réalisation d’un magnétomètre dans le but de mesurer les fluctuations de champ magnétique dans les plasmas spatiaux du système solaire. Des magnétomètres de type Search-coil et Fluxgate sont couramment embarqués sur des satellites et produisent des mesures de haute qualité. De nos jours\, la recherche utilise de plus en plus de petits satellites dont l’archétype est le « Cubsat » qui est un cube de 10 cm de côté. Cependant\, l’instrumentation actuelle ne peut pas être miniaturisée sans compromettre les performances. C’est dans ce cadre que le projet MAROT propose l’élaboration d’un magnétomètre miniature utilisant comme élément sensible des jonctions tunnel magnétiques (MTJ)\, pour mesurer des champs de l’ordre du picotesla. Les jonctions tunnel magnétiques sont des éléments convertissant une variation d’aimantation en variation de résistance\, permettant ainsi de mesurer les variations de champ magnétique. Ces magnétomètres sont déjà utilisés comme capteurs dans de nombreuses applications (automobile\, imagerie médicale\, capteurs dans des systèmes électroniques…) de par leur haute sensibilité au champ magnétique. Cependant\, les MTJ souffrent d’une perte de détectivité à basse fréquence car leur bruit évolue inversement à la fréquence du signal mesuré. Or les basses fréquences (< 100 Hz) sont les fréquences pertinentes pour les plasmas spatiaux. Pour compenser cette limitation\, le capteur MAROT contient des concentrateurs de flux (FC) pour amplifier le champ magnétique sur la jonction. L’optimisation du capteur passe d’une part par l’augmentation de sa sensibilité et d’autre part par la diminution du bruit\, afin d’atteindre une détectivité de l’ordre du pT/√Hz à 10 Hz. Les jonctions tunnels sont constituées d’un empilement constitué de plusieurs blocs : couche de référence\, barrière tunnel\, couche libre. Dans ma thèse\, j’ai utilisé et réalisé des jonctions tunnels à réponse symétrique\, présentant un état antiparallèle à champ nul\, obtenu après un recuit sous champ. Cet état\, ainsi que la configuration macrospin de la couche libre\, minimisant l’hystérèse\, est réalisée en piégeant légèrement la couche libre par une couche antiferromagnétique. Lors de cette thèse\, tout d’abord\, j’ai pu avoir accès à une couche libre à base de FeCoSiB\, couche plus amorphe et plus douce que le NiFe précédemment utilisé\, permettant une amélioration du rapport de magnétorésistance (TMR) d’un facteur supérieur à 2\, jusqu’à 250%. Ces optimisations ont permis de gagner un facteur 3 dans la sensibilité des jonctions. Dans un second temps\, j’ai réalisé des simulations de l’amplification du champ magnétique par les concentrateurs de flux (gain) en fonction des dimensions et caractéristiques de l’entrefer. Cette étude m’a permis de dessiner un nouveau design de capteur dans lequel des jonctions en série-parallèle sont ajoutées dans l’entrefer afin d’augmenter le volume magnétique\, pour réduire le bruit\, tout en maintenant un gain suffisant. Des capteurs avec ce design ont été fabriqués. Les premières mesures indiquent des sensibilités très grandes\, de l’ordre de 2000 %/mT. Les mesures de bruit sont en cours\, et semblent indiquer que les FC\, à base de NiFe déposés par électrolyse\, apportent du bruit supplémentaire. La composition de ces FC sera donc à optimiser afin d’améliorer la détectivité\, actuellement autour de quelques centaines de pT/√Hz à 10 Hz. Pour finir\, j’ai commencé à développer une méthode de hachage de champ magnétique pour réduire le bruit. Une couche magnétostrictive\, déposée sur un substrat piézoélectrique soumis à une tension\, peut voir sa direction d’anisotropie modifiée. Ce dispositif pourra être placé au-dessus de l’entrefer des FC et utilisé comme un interrupteur magnétique\, qui alternativement modifie le flux magnétique sur les jonctions. Un gain d’un facteur au moins 10 sur la détectivité est attendu\, ce qui permettra de s’approcher de l’objectif du pT/√Hz à 10 Hz. \nPlus d’information :https://www.spintec.fr/phd-defense-marot-a-miniature-magnetometer-for-space-exploration/ \nPour suivre la soutenance ​​​en visioconférence : https://univ-grenoble-alpes-fr.zoom.us/j/98769867024 \n_ \n\n\nP​resential access to the conference room at CEA in Gre​​noble requires an entry authorization\, request it before may 16th​​ to admin.spintec@cea.fr

SUMMARY:Lucas GOEHRING (Nottingham Trent University (UK))
DESCRIPTION:Structure formation in paints and coatings\nRésumé : \nPaints and coatings are typically a mix of small particles\, like pigments\, along with a polymer glue or binder. Similar products include inks\, varnishes\, cosmetics\, ceramics and even the lithium-ion battery electrodes that power modern electric vehicles. These materials are prepared as a liquid\, spread over a surface\, and dried.  As anyone who has painted a wall will know\, however\, this process can easily go wrong. Even a well-prepared paint can develop an undesirable skin and wrinkle\, crack\, or peel\, and these coatings can also visibly degrade over time. \nIn this talk I will go through the key stages of film formation\, or how a colloidal dispersion dries.  I will show how small angle scattering experiments (SANS/SAXS) helped to elucidate how the structure of the film changes during drying\, evolving from a dilute gas of particles\, into a transient gel where capillary pressures balance electrostatic repulsion\, to a final aggregated solid. I will then turn to look at how the insight gained has led to a better understanding of mechanical instabilities like fracture\, shear banding\, birefringence\, and peeling\, as well as revealing an unexpected route to colloidal crystallisation. \nFinally\, I will summarise our recent work using neutron scattering techniques to investigate blanching\, a degradation process that can cause a visible whitening in the traditional varnishes that are used as a protective outer coating on many historically and artistically important paintings. \nSpeaker’s website: https://www.ntu.ac.uk/staff-profiles/science-technology/lucas-goehring \n— \nOrsolya Czakkel (College 9 Secretary) \nExternal visitors may ask for a site access to tellier@ill.fr \nZoom link: https://ill.zoom.us/j/95581858117?pwd=hh9paEQj6BF8u9WYzfZkvZaGspe1i3.1  – Passcode: 078610 \n

SUMMARY:Carlotta PORZIO (CERN\, Switzerland)
DESCRIPTION:Experimental activities at the ISOLDE-CERN facility\nRésumé : \nThe ISOLDE factily at CERN is one of the world-leading laboratories for the production of radioactive ion beams (RIBs) with the ISOL (Isotope Separation On-Line) method. More than 1000 isotopes of over 70 chemical elements have been produced via the interaction of a 1.4 GeV proton beam with a variety of target materials. After ionization and mass separation\, the beams can be delivered at low energy or post-accelerated up to about 10 MeV/u using the HIE-ISOLDE linear accelerator. The facility supports a broad scientific program\, spanning nuclear structure studies\, nuclear astrophysics\, materials science\, life sciences\, and investigations of fundamental interactions. \nAmong the experimental setups available at HIE-ISOLDE\, the Miniball gamma-ray spectrometer is employed to investigate both collective and single-particle properties of exotic nuclei. Combined with the post-accelerated radioactive ion beams\, Miniball enables nuclear structure studies via Coulomb excitation and nucleon-transfer reactions. \nThis seminar will provide an introduction to the ISOLDE facility and the ISOL RIB production method\, and an overview of experimental setups and techniques\, with a focus on the Miniball spectrometer. \n— \nHanno Filter (College 3 Secretary \nExternal visitors may ask for a site access to tellier@ill.fr \n
