On the nature of the magnetism in Fe3GeTe2

ORAL

Abstract

Magnetic ordering in layered van der Waals materials is not only of fundamental scientific interest, but also offers a pathway to tailor magnetic properties via confinement and heterostucture engineering. Recent studies have reported both ferromagnetic and antiferromagnetic order in the quasi 2D Fe3GeTe2.[1,2] In this talk we will address these seemingly contradicting results based on first principles calculations, scanning tunneling microscopy and inelastic neutron scattering.
