| English abstract | Chromium substituted copper base spinel ferrites (Ni 0.3 Cu 0.7 )Cr X Fe2− X O4 were prepared by Sol-gel method. Structural, magnetic and electrical properties were studied by utilizing an X-ray diffractometer, vibrating-sample magnetometer, and precision LCR-meter using labtracer software. The X-ray diffraction analysis confirmed the formation of single phase fcc structure of the samples. The lattice constant and crystallite size decreased from 8.37-8.23 Å and 53.09-35.36 nm, respectively with increasing content of Cr3+ ions. From Magnetization Vs Applied field loops it was observed that the saturation magnetization decreased and coercivity increased with increasing content of Cr3+ ions. Dc resistivity increased with increase of Cr3+ concentration and decreased with increase in temperature which shows the semiconducting behavior of ferrites. The dielectric constant, dielectric loss, and tangent loss decreased with increase of Cr3+ concentration. The dielectric constant follows bilayer Maxwell Wagner model and Koop’s phenomenological theory while ac conductivity increased with increasing frequency following Jonscher’s power law |
