Microstructure Characterization of ZnFe2-xMxO4 (M = Bi, Y and x = 0.1, 0.2) Ferrites by the Rietveld Refinement
Ferrites -ray diffraction lattice parameter paramagnetic magnetization
2010/4/12
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 t...
Refinement of Monoclinic ReO2 Structure from XRD by Rietveld Method
Monoclinic ReO2 Structure XRD Rietveld Method
2010/10/26
ReO2 presents two crystalline variants, with monoclinic and orthorhombic structures. The former is metastable and irreversibly transforms to an orthorhombic structure above 460oC. The structure of the...
