Abstract:
Topological semimetals, whose low energy electronic structure possesses several band contact points or lines, are generally expected to exhibit novel transport responses. Particularly, when combined with magnetism, topological band degeneracy is intimately coupled with spin configurations or orientations, offering an efficient magnetic control of electronic conduction. In this talk, I will introduce van der Waals (vdW) magnets, where combination of magnetism, spin-orbit interaction, and orbital-driven topological band degeneracy gives rise to large magnetotransport responses and magnetic tunability. These findings demonstrate that topological vdW magnets have great potential for various spin-dependent electronic functionalities.
