Ferrite samples of the composition Cu1 − xZnxFe2O4 (0.0 ≤ x ≤ 1.0) were synthesized by chemical coprecipitation. The samples exhibited a single‐phase cubic spinel structure and the saturation magnetization of the samples was found to increase with increasing Zn content, when x ≤ 0.4; and then decreased with increasing x. The dependence of magnetization on cation distributions in the ferrite samples...
The effects of heat‐treatment temperature, THT, and heat‐treatment time, tHT, on the structural and magnetic properties of manganites with a nominal composition La0.6Sr0.1MnO3−δ, prepared by the sol–gel method, were investigated. The XRD spectra indicate that the samples have two phases with the perovskite being the dominant phase and Mn3O4 being the second phase. It was found that...
