Enhancement of Magnetic Anisotropy Energy in Heavy Metal/layered Magnet Heterostructure Induced by Strong Spin Orbit Coupling

ORAL

Abstract

Layered ekchromium telluride (Cr1+xTe2) is known as itinerant ferromagnet with self-intercalated Cr inside the Van der Waals gap based on 1T CrTe2. Recently Chromium telluride (Cr1+xTe2) family draw a large interest due to their unique physical properties such as magnetic Skyrmions [1] and topological Hall effect [2] etc. As strong potential candidate to realize 2D-spintronics, numerous researches had done to understand the physical properties of Chromium telluride (Cr1+xTe2). However, manipulation of magnetic properties of Chromium telluride (Cr1+xTe2) had not been performed yet. Here, we investigate the controlling of the magnetic properties of Cr2Te3 ultra-thin films forming heterostructure with heavy metal to induce interface spin-orbit coupling. With complementary transport and spectroscopic evidence, we will address the origin of observed manipulation of magnetic properties of ultra-thin film system.
