Abstract

The cobalt substituted Nickel-Zinc ferrites with the composition Ni0.95-xZn0.05CoxFe2O4, for x= 0.01, 0.02, 0.03, 0.04, 0.05 and 0.06 were synthesized by the soft chemical route method and were found to have cubic system of ferrimagnetic spinel using XRD. The grain sizes decreases significantly with the cobalt content (x) and are 1.62-1.36nm for x = 0.01 to 0.06 which are small enough to produce appropriate high density recording media. The particle size is found to be in the range 29-22 nm with the help of SEM. Their magnetic properties determined with VSM show the dependency on the exchange interaction due to the cobalt substitution between the metal ions of tetra and octahe.
