The first bulk n = 3 brownmillerite structure Ca2MnAlO5.5 has been synthesized by high-pressure oxidation of the n = 1 brownmillerite phase, Ca2MnAlO5, such that alternate AlO4 tetrahedral layers are oxidized to AlO6 octahedra. Rietveld analysis of r

The crystal and magnetic structures of the two related phases, Sr2MnGaO5 and Ca2MnAlO5 are reported. Rietveld analysis of neutron powder diffraction has revealed that both phases adopt the brownmillerite structure. Subtle differences in structure lea

Hydrothermal techniques have been used to synthesize samples of α -Fe 2 O 3 in which ca. 10% of the Fe cations have been replaced by Sn 4+ , Ti 4+ , and Mg 2+ . Neutron powder diffraction data show the dopant ions to occupy both interstitial and sub
