Magnon mode in alpha-MnS Raman spectrum

Gerasimova, Julia V.; Abramova, Galina M.; Zhandun, Vyacheslav S.; Vtyurin, Aleksandr N. Journal Of Raman Spectroscopy

Raman spectra of manganese monosulphide (alpha -MnS) with NaCl structure in the temperature range 5-300 ? are presented. A new peak at 22 cm(-1) has been found at low temperatures. The temperature dependence of this peak made possible to...
