The thermal conductivities of near stoichiometric (U0.7-zPu0.3Amz)O2 solid solutions (z = 0.05, 0.10, and 0.15) have been measured between room temperature (RT) and 1473 K under oxygen partial pressure controlled atmosphere. Thermal conductivities we

Negative thermal expansion (NTE) induced by simultaneous mechanisms, that is, charge transfer and polar-nonpolar transitions, was observed for the first time in BiNi1-xFexO3 (0.25 ≤ x ≤ 0.5). The low-temperature phase was found to have a polar st

BiCoO3 is a PbTiO3 type of perovskite oxide with a giant tetragonal distortion (c/a = 1.27) that shows a pressure-induced transition from tetragonal to orthorhombic phases accompanied by a large volume shrinkage at 3 GPa. In this study, we carried ou
