Abstract
The temperature dependences of the peak energies and intensities of the high-energy band (band A) and the low-energy band (band B) of the spin-wave-assisted photoluminescence in MnO have been studied at low temperatures down to 5 K. Side bands due to combinations of the elementary excitations (Mn2+ excitons, spin-wave quanta (magnons), TO phonons and LO phonons) were also observed below 40 K as shoulders appearing on the high-energy side of band A.Keywords
