The Mössbauer and X-Ray Studies οf the Spinel Ferrites Cu0.5Fe0.5Cr2Se4Cu_{0.5}Fe_{0.5}Cr_2Se_4 and Cu0.2Fe0.8Cr2Se4Cu_{0.2}Fe_{0.8}Cr_2Se_4 Prepared by the Ceramic Method

Seleno-spinels with nominal chemical composition $Cu_{0.5}Fe_{0.5}Cr_2Se_4$ and $Cu_{0.2}Fe_{0.8}Cr_2Se_4$ were prepared as polycrystalline samples using ceramic method. The assumed composition was verified by wavelength-dispersive X-ray fluorescence spectrometry. The X-ray analysis was carried out in order to make phase analysis and to compare its results with those obtained with the Mössbauer spectroscopy
