Spin and cation order in AMn3B4O12 perovskites
A-site-ordered perovskite oxides with formula AA'3B4O12 have a rich variety of physical and chemical properties. Most have Jahn-Teller active Cu2+ or Mn3+ at the square-planar... -
High Pressure Structural Study of BiCoO3
BiCoO3 is a perovskite type material recently prepared by high pressure-high temperature synthesis in Kyoto. It has a distorted acentric perovskite structure with order of high... -
High-pressure neutron diffraction studies of valence transitions in ACu3Fe4O12
Two new A-site ordered perovskite structure oxides, CaCu3Fe4O12 and LaCu3Fe4O12, were recently synthesized under high-pressure and high-temperature conditions in Kyoto. These... -
Structural study of BiNiO3 at high pressures and low temperatures
BiNiO3, synthesized at high pressure, has the unusual charge distribution Bi3+0.5Bi5+0.5Ni2+O3 with ordering of Bi3+ and Bi5+ charges on the A sites of a highly distorted...
