Coherent helicity-dependent spin-phonon oscillations in the ferromagnetic van der Waals crystal CrI3
Abstract
CrI3 is a van der Waals material which exhibits magnetic ordering down to the monolayer limit. Here, using ultrafast optical spectroscopy, Padmanabhan and Buessen et al. investigate the coupling between the magnetically ordered spins and lattice distortions, finding a coherent spin-coupled phonon mode.
