Structural, optical, dielectric, and magnetic properties of Zn-doped copper ferrite—sol–gel approach

The various compositions of zinc-doped copper ferrite nanoparticles were prepared through a sol–gel process. The structural analysis is carried out through X-ray diffraction (XRD) and a cubic spinel structure is identified. The functional analysis was carried out through Fourier transform infrared red spectroscopy (FTIR). The microstructure and the element analysis were carried out through SEM with EDAX. The regular and randomized spheres of nano-size are found in the surface analysis. Some marginal absorption in optical behavior was found through UV–visible spectroscopy. The magnetic behavior was investigated through a vibration sample magnetometer. The hysteresis loop indicated the ferromagnetic behavior of ZnCu ferrite. The frequency dependence of the dielectric constant, dielectric loss, and its conductivities were studied through an LCR meter. Further, the interfacial polarization effect was studied significantly. Finally, the electrochemical response was analyzed through a cyclicvoltameter. The relative merits and demerits are interpreted and discussed extensively.
