Magneto-Raman study of the Neel-type Antiferromagnet MnPSe<sub>3</sub>

ORAL

Abstract

The discovery of 2D magnetism in van der Waals materials such as CrI3 and Cr2Ge2Te6 demonstrated that long range magnetic ordering can survive in the monolayer limit, given that the material has sufficiently large anisotropy. MnPSe3 is a layered material with Neel-type antiferromagnetic spins lying parallel to the basal plane. We perform a systematic magneto-Raman study of MnPSe3. Multiple excitation laser wavelengths were used. With resonant Raman condition, we study the temperature and magnetic field dependence of the Raman spectrum of single crystal MnPSe3. A drastic shift in the phonon spectrum across TNeel is observed. We compare the spin-phonon coupling between bulk and thin samples.
