Tailoring magnetism in self-intercalated Cr<sub>1+δ</sub>Te<sub>2</sub> 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.
