Structural, Electrical, Dielectric, and Magnetic Properties of Cd2

In the present investigation structural, electric, magnetic, and frequency dependent dielectric properties of ferrite nanoparticles (NPs) (where , , , and 0.8) prepared by sol-gel autocombustion method were studied. The crystallite size () (46.89~58.40 nm) was estimated from X-ray diffraction data with the postconfirmation of single phase spinel structure. Spherical shaped, fused grain nature with intergranular diffusion in NPs was observed in scanning electron micrographs. The value of loss tangent () decreases exponentially with an increasing frequency indicating normal Maxwell-Wagner type dielectric dispersion due to interfacial polarization. Decreasing values of Curie temperature () from 860°C to 566°C with increasing Cd2
