Ti
O
prepared by rapid quenching. The intermediate structure which appears during the re-crystallization process consists of two phases; one is pyrochlore Bi
TiO
phase and the other is a stacking-fault induced structure under the excessive Bi condition. The microstructure of the stacking-fault induced structure was investigated by synchrotron X-ray diffraction. In the case of a large number of BiO, some are inserted between the pseudo-perovskite layers of BiTiO, and a non-stoichiometric BiWO
-like structure is stabilized.

Times Cited Count：3 Percentile：18.87(Physics, Applied)High energy XAFS studies of Sm: K-edge in Sm2Fe17Nx with x = 0.0, <= 0.1, 0.5, 2.0 and 3.0 were carried out at room temperature in order to clarify the relation between the local structure around the Sm-atom and the change of the magnetic property due to the absorption of nitrogen atom. In the XANES region, we firstly found the change of Sm electron state by nitriding because of the change of the shape in the absorption edge junp. In the result of the EXAFS spectra, we confirmed that the Sm-Fe distance was expanded monotonously due to the absorption of N-atom.
