Partial substitutions of Zn2+ ions with Cu2+ and Co2+ ions in Ni0.33Zn0.67Fe2O4 ferrite were investigation. The temperature dependences of the magnetic susceptibility χ(T) was used on study of the superchange A-B interaction, and A-A or B-B interaction for substituted NiZn ferrites.
Keywords: susceptibility, magnetic moment, Curie temperature, ferrites, super exchange interaction
