Popis: 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.
