Phonons regulate covalency: a new way to modulate the magnetism and Curie temperature of CrI 3
Abstract
by 6.63% and 4.77%. The underlying mechanism is that E4g and A11g weaken the covalency and super-exchange coupling between Cr and I atoms, whereas the E3u and A22g modes strengthen them. Our work offers valuable theoretical insights for the application of 2D magnetic materials in spintronics.
