   Partial substitutions of Zn²⁺ ions with Cu²⁺ and Co²⁺ ions in Ni_0.33Zn_0.67Fe₂O₄ 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
