Abstract

Spinel ferrites have received extended discussions among different ceramic magnetic nanoparticles due to dependence of its physiochemical properties on the fabrication processes and composition. In this context, copper doped cobalt ferrites (Co1-xCuxFe2O4) with different Cu2+ doping content (i.e., 0.0 ≤ x ≤ 0.4) were successfully fabricated via hydrothermal method. The impact of exchanging divalent cobalt (Co2+) cations by divalent copper (Cu2+) cations on structure-magneto-optic characteristics of Co1-xCuxFe2O4 ceramic magnetic nanoparticles was studied. The spinel single cubic phase of prepared samples with the signature of CuO phase for x ≥ 0.2 was proved by powder X-ray diffraction (XRD) and infrared spectroscopy (IRS) studies. The particle size distribution depending on the Cu2+ doping content was studied by means of XRD and Transmission electron microscopy (TEM) analysis. The particle …
