Microstructure Characterization of ZnFe_{2-x}M_{x}O_{4} (M = Bi, Y and x = 0.1, 0.2) Ferrites by the Rietveld Refinement


Abstract: The microstructure of the ferrites was analyzed by the Reitveld refinement method. The Bi-containing ferrites revealed a decrease in the lattice parameter as the Bi^{3+} concentration is increased, due to the distortion of the ferrite lattice. There was a minor distortion in the ZnFe_{1.9}Y_{0.1}O_4 ferrite lattice. A minor yttrium oxide phase coexisted with the ZnFe_{1.8}Y_{0.2}O_4 spinel phase.

Keywords: Ferrites; X-ray diffraction; lattice parameter; paramagnetic; magnetization.
