摘要：

Structural parameters along with magnetic and electrical behaviour of nanosize Co-Ni spinel ferrites synthesized by co-precipitation method are reported. The crystallite size was found to be within the range of 14-21 nm. The Curie temperature increases with Ni concentration. The activation energy and drift mobility are determined from the DC electrical resistivity measurements. The dielectric constants and loss factors as a function of frequency are also reported.
