(1) Microstructure Characterization of ZnFe_2-xM_xO₄ (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 Bi³⁺ concentration is increased, due to the distortion of the ferrite lattice.

There was a minor distortion in the ZnFe_1.9Y_0.1O₄ ferrite lattice. A minor yttrium oxide phase coexisted with the ZnFe_1.8Y_0.2O₄ spinel phase.
