Distinct Magneto-Optical Response of Frenkel and Wannier Excitons in CrSBr

Abstract

This study shows that CrSBr hosts Frenkel-like and Wannier-Mott-like excitons whose distinct spatial character explains their contrasting sensitivity to magnetic order and lattice vibrations, challenging the standard dichotomy in describing excitons.
