Abstract Raman spectra of manganese monosulphide (α‐MnS) with NaCl structure in the temperature range 5–300 К 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 calculated with Munich SPRKKR‐package.
