Single phase of Fe super(3+)-doped alpha -Ga sub(2-x)Fe sub(x)O sub(3) ( alpha -GF sub(x)O, x = 0.1, 0.2, 0.3, 0.4) is synthesized by treating the beta -Ga sub(2-x)Fe sub(x)O sub(3) ( beta -GF sub(x)O) precursors at high temperatures and high pressures. Rietveld refinements of the X-ray diffraction...
