Ultrafine particles of ( 0.20) were prepared by using co‐precipitation method. X‐ray diffraction studies show that the samples have cubic spinel structure and average crystallite size of and are 49.84 nm and 27.73 nm respectively. Dielectric and magnetic properties have been studied by impedance analyzer and magnetic properties of the ferrite system were studied using VSM respectively. ions modulate significantly the electric, dielectric and magnetic properties of cobalt spinel ferrites.
