Tailoring magnetism in self-intercalated Cr1+δTe2 epitaxial films

ORAL

Abstract

Controlling magnetic properties, including Curie temperature and magnetic anisotropy, in two dimensional ferromagnets are highly demanded for spintronics application. Here, we investigated magnetic properties of Cr1+δTe2 epitaxial films with varying δ. We found enhancement of Curie temperature above room temperature and rotation of magnetic anisotropy from out-of-plane to in-plane. Theoretical calculations suggest that anti-ferromagnetic interaction perpendicular to plane direction becomes stronger as increasing δ, which plays an important role in the experimental observations.
