Hematophanite, a derivative of the perovskite structure
Mineralogical Magazine, 1973SummaryHematophanite, ideally Pb4Fe3O8Cl, is tetragonal, space group P4mm, with a = 3·92 and c = 15·31 Å. The crystal structure, which has been refined to an R-factor of 9·1 %, may be described as an interlayering of perovskite-like units with a cesium chloride or, alternatively, a nadoritelike unit. The nadorite-like part consists of a double layer of

Perovskite and Related Structure Systems
1998Perovskite and perovskite-related structures are important crystallographic structures particularly for oxide functional materials because most of the newly discovered functional materials belong to this category (for a complete list of perovskite structures, see Galasso, 1969, 1990).

Structural softness in photovoltaic perovskites
Applied Physics LettersPerovskite photovoltaics (PVs) are a compelling candidate as a next-generation energy harvesting technology owing to the outstanding optoelectronic properties, low cost, and facile fabrication of perovskite materials. In the meantime, unsolved issues in perovskite stability still challenge the prospect of final commercialization. Recently, many studies

New Relaxors with the Perovskite Structure
Ferroelectrics, 2010Perovskites PbBO3 with multiple substitutions in the B-positions were synthesized. Ceramic samples with n = 2–6 (n is the number of different B-ions) were studied using X-ray diffraction, and measurements of dielectric permittivity at frequencies 12 Hz–100 kHz and temperatures 77–450 K. It has been shown that the samples are of the perovskite structure,
