Abstract
A series of copper (Cu2+) doped Zn0.4Co0.6-xCe0.1Fe1.9O4(x = 0.0, 0.15, 0.30, 0.45, 0.60) nanoparticles were synthesized via co-precipitation route in order to evaluate different properties like the structural, optical, electrical and magnetic through XRD, UV-VIS, SMU with two probes and VSM methods. The XRD patterns confirmed the formation of cubic spinel structure of the prepared samples. Replacement of Co2+ ions with Cu2+ ions have been confirmed by X-ray diffraction patterns. FTIR and UV–Vis also confirmed this replacement. The electrical parameters like DC resistivity, activation energy, and drift mobility have been evaluated to confirm the semiconductor nature of the spinel ferrites. The Curie temperature declines on replacement of Cu2+ ions with Co2+. The magnetic parameters like Bohr magnetic moment, anisotropy constant, initial permeability, Y–K angles, coercivity, and remanence ratio have been measured and determined. The saturation magnetization (Ms) and remanence (Mr) show remarkable decreasing trend with Cu2+ ions concentration.
