Interlayer magnetism in Fe3−xGeTe2

ORAL

Abstract

While most studies have concluded the interlayer ordering to be ferromagnetic, there have also been reports of interlayer antiferromagnetism in Fe3−xGeTe2. From neutron diffraction experiments, scanning tunneling microscopy (STM) and density functional theory plus U calculations we conclude that the layers of Fe3−xGeTe2 are coupled ferromagnetically.
