The samples under investigation of the formula Ni0.7Zn0.3CuzY0.01Fe1.99-zO4; 0≤z≤0.1 were prepared using standard ceramic technique from pure analar oxides (BDH). IR spectroscopic analysis has been carried out for all samples. The magnetic susceptibility for the samples was performed using Faraday's method as a function of temperature and magnetic field intensities. The data were interpreted in view of the exchange interaction constant that takes place between the different cations. Variation of TC with Cu content in the samples was observed.
