Detecting Large Thermal Hall Effect in MnPS3

ORAL

Abstract

The phenomenon of thermal Hall effect in insulating materials has recently attracted the interest of the scientific community. In this talk, we expand on the thermal Hall measurement to low temperatures in an insulating antiferromagnet, MnPS3. We discuss some possible origins causing our large observed thermal Hall signal, including intrinsic Berry curvature, magnon-phonon hybridization, and magnon-phonon skew scattering. Additionally, we discuss the temperature and magnetic field dependence of the Hall angle, kxy, and kxx in both antiferromagnetic order and spin-flop transition.
