SUMMARY:Frédéric Bonell I Molecular beam epitaxy of 2D magnets and magnetic van der Waals heterostructures for spintronics
DESCRIPTION:\nFrédéric Bonell (Spintec-Grenoble)\n\n\n\nThe recent discovery of van der Waals 2D magnets has opened exciting opportunities to explore low dimensionality magnetism, proximity phenomena in heterostructures and all-van der Waals spintronics [1]. While most research in this area is currently performed with nanoflakes mechanically exfoliated from bulk crystals, molecular beam epitaxy is emerging as a powerful method to grow large-area 2D materials with fine tuning of the composition and control of the thickness down to the 2D limit.\n\n\n\nI will review our recent progress in the fabrication of 2D magnets by molecular beam epitaxy, including diluted 2D semiconductors [2], 2D metallic alloys [3] and (Fe,Co)NGeTe2 intrinsic ferromagnets [4]. I will also present an example of epitaxial van der Waals heterostructure in which a 2D magnet is associated to a topological insulator. In such an heterostructure, large spin-orbit torques are observed, enabling current-driven magnetization switching [5].\n\n\n\nREFERENCES\n\n\n\n[1] Kurebayashi et al. Nature Rev.
