Abstract : The energy distribution of donor-bound magnetic polarons is studied in CdMnS and CdMnSe alloys, using the spin-flip Raman scattering technique. The influence of magnetic fluctuations on the lineshapes is proved Evidence of the superparamagnetism of giant moments associated to magnetic polarons is also reported.

Keywords : cadmium compounds II VI semiconductors magnetic impurity interactions magnetic semiconductors magneto optical effects polarons Raman spectra of inorganic solids superparamagnetism
