Language：Japanese Publisher：The Physical Society of Japan

<p>自発分極は試料内部の静電ポテンシャルを傾斜させる。強誘電体の原子軌道エネルギーはこの傾斜に応じて系統的に変化すると考えられる。この現象はバンドベンディングと呼ばれ40年以上に渡り予想されてきた。今回，BaTiO_3_においてバンドベンディング現象を直接的に観測したので報告する。本研究において得られた実験結果は，エピタキシャル製膜された強誘電体薄膜試料と深さ分解光電子分光実験を組み合わせることで初めて達成できた。</p>

XANES study of charge ordering on the spin-Peierls phase transition of α′-NaV2O5

Takahisa Shobu, Takahisa Shobu, Yukio Noda, Emi Ninomiya, Hiroshi Sawa, Shin Ichi Nagamatsu, Takashi Fujikawa, Yutaka Ueda, Masahiko Isobe, Naoshi Ikeda, Tomoya Uruga

Journal of Synchrotron Radiation 8 746 - 748 2001.3

α′-NaV2O5 transforms at TC = 34K, and the origin of the phase transition seems to be caused by the charge order and spin-Peierls mechanism. However the experiments which reveal the existence of charge order are very little. We measured XANES of V atoms which relates to the valence of V. It was found that the valences of V atoms in NaV2O5 were V4.5+ in the high temperature phase by comparing pre-edge and XANES of NaV2O5 with that of LiV2O5, CaV2O5 and V2O5. The analysis of EXAFS also shows the environment of the V4.5+ state.

Language：Japanese Publisher：The Japan Society of High Pressure Science and Technology

In this article, we review recent activities at BL02B1 at SPring-8 in the field of single-crystal and high-pressure X-ray diffraction experiments. A comparison of experiments performed two decades ago with the new frontier experiments is also shown. Special attention is paid to the importance of the quantitative arguments. The chracteristics of the single-crystal and high-pressure experiments are also compared with the powder-sample and high-pressure experiments.
