The structural complexity of perovskites
Physical Chemistry Chemical Physics, 2022Information theory is used to calculate structural complexities of various perovskite-type materials, showing that complexity scales with the size of the pseudocubic ReO3-type [BX3]n− network and available distortion schemes.

Elasticity of CaIrO3 with perovskite and post-perovskite structure
Physics and Chemistry of Minerals, 2010Compression behaviors of CaIrO3 with perovskite (Pv) and post-perovskite (pPv) structures have been investigated up to 31.0(1.0) and 35.3(1) GPa at room temperature, respectively, in a diamond-anvil cell with hydrostatic pressure media. CaIrO3 Pv and pPv phases were compressed with the axial compressibility of β a > β

Nuclear ferromagnetism in a perovskite structure
Physical Review Letters, 1991Ferromagnetism of $^{19}\mathrm{F}$ nuclear spins in a monocrystalline ${\mathrm{KMgF}}_{3}$ sample has been observed by NMR in the presence of a high magnetic field and in the microkelvin temperature range. The three $^{19}\mathrm{F}$ spins of one crystalline cell are equivalent when the field is along the [111] axis of the crystal and inequivalent ...

Tilting structures in perovskites
Crystallography Reports, 2004Thirty five low-symmetry tilting phases of the octahedra in which the atoms located at the initial octahedral position remain equivalent are derived for the perovskite structure at the k 10(X), k 11(M), and k 13(R) points of the Brillouin zone.

Structure and photocatalytic property of perovskite and perovskite-related compounds
Materials Chemistry and Physics, 2006Abstract Perovskite (ABO 3 ) and perovskite-related (brownmillerite, A 2 B 2 O 5 ) compounds were prepared by citrate–nitrate combustion method. Crystal structure was verified by X-ray diffraction. Absorbency was determined by UV–vis spectrophotometer.

Electronic structure of perovskite-type compounds
Physical Review B, 1990On calcule les structures des bandes des composes de type perovskites KMF 3 (M=Mn, Fe, Co, Ni, Cu et Zn) sur la base de la methode de liaison forte generalisee de Huckel. On presente les densites partielle et totale des etats. Comparaison avec les donnees experimentales disponibles.

Elasticity of MgSiO 3 in the Perovskite Structure
Science, 1989The single-crystal elastic moduli of MgSiO 3 in the perovskite structure, the high-pressure polymorph of MgSiO 3 pyroxene, have been determined. The data indicate that a mantle with either pyrolite or pyroxene stoichiometry is compatible with the seismic models appropriate to the earth's ...
