The study of spinel ferrite ion sites is an important aspect to optimize its structure. In this report, homogeneous and stable mixed spinels CoFe2O4 and MgFe2O4 were synthesized by a simple sol–gel combustion method. The Curie temperature is higher than 400 K, so the Mössbauer spectrum at room temperature shows a typical magnetically ordered Zeeman sextet. The change in the hyperfine magnetic field is consistent with the change in the saturation magnetization, which can be explained by the change in the superexchange contribution between each...
