چکیده انگلیسی
Two series of copper ferrites are prepared using the chemical compositional formula Cu 1.0 Fe 2.0-2x Mo x O4.0 and Cu 1.0-3x Fe 2.0 Mo x O4.0. They are calcinated at 750 C and sintered at 950C. The grain size initially decreases with Mo6+ concentration. while it found to increase from x = y = 0.06 (Mo6+) onwards. The monotonic increase of Tc is found in C series materials while in F series it observed to decrease at intermediate values of x. Variation of magnetization has been explained on the basis of Neel's model of magnetic interactions and Yafet-Kittel angle existence. The initial permeability (μi) increases at room temperature followed by its fall with the increase of F as well as C series. The observed deviation between experimental and theoretical magnetic moment values is explained in terms of Y-K angle occurrence.
