Abstract

Abstract: We investigated the effects of Co 2+ and Cu 2+ substitution on the super-exchange interactions in Ni–Zn nanoferrites. The cation distribution technique was taken into account to explain the results. To authenticate the cation distribution, we have estimated the cation distribution in the light of X-ray diffraction method, Mössbauer spectroscopic analysis, and magnetization study. Statistical model based on the cation distribution was used to calculate the Curie temperature. The values of magneton number n B and Curie temperature T C calculated by using the cation distribution is found to be in agreement with the experimentally obtained values.
