Microstructure characterization of $ZnFe_{2-x}M_xO_4$(M = Bi, Y and x = 0.1, 0.2) ferrites by the Rietveld refinement

Özet

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.
