Different samples for ferrite compounds of system Co_1+xSn_xFe_2-2xO₄, where hence x takes values 0.25, 0.5, 0.75 and 1, were synthesized by using ceramic technique method from their metal oxides of their purity more than 99.9%. The firing process was done at temperature 1200°C, and a soaking time of about 24 hours. X-ray diffraction (XRD) patterns of all used samples showed the cubic phase of spinel structure. The infrared spectra results have been obtained and analyzed, also the frequency bands were assigned, and it was found to be compositional parameter. The Mossbauer spectra technique at room temperature also has been used, and it indicates that all the compounds are principally paramagnetic. Only the iron rich compound is order ferrimagnetically and has magnetic transition temperature higher than room temperature. The crystal structure was refined for all the samples using whole pattern-fitting analysis of Reitveld method.
