Resumo

Temperature dependence of Raman spectra in the frequency interval 100... 1 200 cm1 in the 100...300 K range temperature has been investigated in the substance of CoxMn1-xS solid solutions. A Raman spectra study has uncovered evidence of strong orbital fluctuations that manifest itself in kind of composite line shape at ω2 273...298 cm-1, arisen from splitting of phonon modes with different temperature dependences of the intensity below the orbital ordering transition.
