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... -
Crystal and magnetic structures of new ruthenate perovskites
Ruthenate perovskites have a diverse range of electronic properties originating from electron-electron correlations within broad 4d bands. We have recently investigated the high... -
Anion Order in BaTaO2N
Transition metal oxynitrides with the perovskite structure type are an emerging class of functional materials with a variety of interesting optical, photocatalytic, dielectric... -
Short range magnetic order in the compositionally modulated Bi2Cr4/3Ni2/3O6 p...
It is particularly challenging to synthesize a novel multiferroic material as it seems that the mechanisms that allow ferromagnets and ferroelectrics to work are mutually...
