Аннотация: 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 attribute it to the magnon mode at k = 0. This is in good agreement with the magnon wavenumber Показать полностьюcalculated with Munich SPRKKR-package.
