SUMMARY:Pierre PUJOL (LPT\, Univ. Toulouse)
DESCRIPTION:Skyrmions\, bimerons and their effect on itinerant electrons\nRésumé : \nMagnetic skyrmions and bimerons are topological spin textures that exhibit remarkable stability at finite temperatures. In this talk we will discuss a variety of models exhibiting different phases (fluid and crystallines) of these topological spin textures that are tunable with temperature\, magnetic field or strain. We’ll also discuss their effect on itinerant electrons\, and in particular the presence of bound states and one dimensional (i.e.\, like edge) electronic transport. \n_ \nContact : elsa.lhotel@neel.cnrs.fr

SUMMARY:Yayoi TAKAMURA (University of California\, Davis (USA))
DESCRIPTION:Tailoring Magnetic Spin Textures in La0.7Sr0.3MnO3-Based Micromagnets\nRésumé : \n\nThe development of next-generation computing devices based on spintronics and magnonics requires an understanding of how magnetic spin textures can be tailored in patterned magnetic materials. Within the wide range of magnetic materials available\, complex oxides such as ferromagnetic (FM) La0.7Sr0.3MnO3 (LSMO) and antiferromagnetic (AF) La1-xSrxFeO3 (LSFO) provide an ideal platform for tailoring magnetic spin textures when lithographically patterned as nano/micromagnets. This unique tunability arises due to the strong interactions among charge\, spin\, lattice\, and orbital degrees of freedom. In this talk I demonstrate how an intricate interplay exists between shape and magnetocrystalline anisotropy energies as well as exchange coupling interactions at LSMO/LSFO interfaces. Therefore\, the resulting AF and FM spin textures can be controlled using parameters such as the LSMO and LSFO layer thicknesses\, micromagnet shape\, and temperature [1]-[3]. These spin textures are imaged using x-ray photoemission electron microscopy for a variety of shapes (circles\, squares\, triangles\, and hexagons with their edges oriented along different low-index crystallographic directions) with and without their core regions removed (“donut structures”). LSMO nanomagnets are also patterned into artificial spin-ice (ASI) structures [4]-[5]\, where large arrays of nanomagnets are arranged in geometries where all the magnetic interactions cannot be satisfied simultaneously. While one might expect shape anisotropy to dictate Ising states in the nanomagnets\, the unique combination of magnetic parameters associated with LSMO enables the formation of both Ising and complex spin textures (CSTs) based on the nano-island width and spacing. These CSTs consist of single and double vortices and alter the nature of dipolar coupling among nanomagnets\, giving rise to exotic physics in the ASI lattices. These studies demonstrate that complex oxides provide a unique platform for engineering FM and AF spin textures for next-generation spin-based devices. \n\nY.

SUMMARY:Valeria DEL CAMPO (Physics Department\, Universidad Técnica Federico Santa María\, Chile)
DESCRIPTION:Graphene in photovoltaic solar energy : results and challenges\nRésumé : \nGraphene has attracted significant interest in photovoltaic applications due to its unique combination of high electrical conductivity\, optical transparency\, mechanical flexibility\, and chemical stability. Despite these advantages\, several scientific and technological challenges still limit its integration into high-performance solar cells. This seminar presents recent results from our research group on the use of graphene in different photovoltaic technologies\, with particular emphasis on the role of interfaces and surface electronic properties. \nFirst\, the implementation of graphene as a transparent conductive electrode in silicon heterojunction (SHJ) solar cells will be discussed. In this context\, graphene offers a promising alternative to conventional transparent conductive oxides\, while enabling new device architectures. The second part of the talk will focus on the use of graphene as an encapsulation layer to stabilize copper oxide hole-transport layers in perovskite solar cells. While graphene can provide effective protection against degradation processes\, the subsequent deposition of high-quality perovskite films onto graphene-covered surfaces presents significant difficulties due to the surface chemistry and wetting properties of graphene. \nFinally\, the seminar will address the characterization of surface electronic properties through work function measurements and inverse photoemission spectroscopy. By probing the electronic structure and energetics of graphene-based interfaces\, these techniques contribute to a deeper understanding of charge transport mechanisms\, which remain among the main challenges limiting the implementation of graphene in high-efficiency photovoltaic devices. \n  \nShort Bio/CV \nDr. Valeria del Campo is an Associate Professor in the Physics Department at Universidad Técnica Federico Santa María (Chile)\, where she currently serves as Head of the Engineering Physics Program. She coordinates the Solar Sustainable Solutions research line at the Solar Energy Research Center (SERC Chile)\, a multidisciplinary center dedicated to advance in public policies based on scientific findings. \nHer research interests focus on photovoltaic solar energy\, graphene and other advanced materials for solar cells\, and the impact of environmental factors such as dust deposition on photovoltaic performance. Her work combines surface and interface characterization with the development of materials and technologies for high-efficiency and sustainable solar energy conversion. \n_ \nContact : deborah.verger@grenoble-inp.fr \n
