Ultrafast dynamics in MnPS<sub>3</sub> studied by time-resolved optical spectroscopy

ORAL

Abstract

The van der Waals insulator MnPS3 exhibits a magneto-electric type antiferromagnetic order that persists down to the few layer limit. Recently it has been shown that this antiferromagnetic order parameter can be measured using optical second harmonic generation (SHG). In this talk, I will report time-resolved SHG and linear reflectivity measurements on MnPS3, demonstrating ultrafast modulation of its electronic properties via both thermal and non-thermal mechanisms.
