Modulation of magnetism across the van der Waals interfaces

ORAL

Abstract

A van der Waals (vdW) heterostructure provides an indispensable material platform in modern condensed-matter researches. There, weak interlayer bonding nature ensures formation of an atomically-abrupt heterointerface beyond fundamental constraint imposed by lattice matching condition, while strong electronic coupling enables creation of an emergent electronic ground state that is missing in individual materials. Here we fabricated vdW heterostructures by molecular-beam epitaxy, where a new type of 2D magnet, vanadium selenide epitaxial thin film1, was incorporated. In the presentation, we will show transport properties of those magnetic heterostructures, and discuss the interface proximity effect on 2D magnetism. [1] M.
