Outline of Final Research Achievements

At SPring-8 BL11XU, we have developed highly sensitive synchrotron Mossbauer diffractometer, which enables us to measure the crystal-site-selective spectra of the natural iron specimens. With this apparatus, we have succeeded, for the first time, in observing the pure nuclear Bragg reflection from the natural iron a-Fe2O3 single crystal. Then we have succeeded in obtaining the crystal-site-selective spectra of the natural iron Fe3BO6, Fe3O4, and Y3Fe5O12 by using the pure nuclear Bragg reflections. We also have attempted to examine the charge order in LuFe2O4 by using the pure nuclear Bragg reflections.

Academic Significance and Societal Importance of the Research Achievements

メスバウアー分光は,ダイナミックかつミクロスコピックなプローブであり,鉄系化合物の磁性や電子状態の研究に極めて有効な測定手段である。しかし,多くの場合,試料が結晶学的に複数の鉄サイトを持つため,スペクトルが複雑化して解析が困難になる。これに対して,メスバウアー回折を用いれば,結晶サイト選択的スペクトルが測定可能となり,高精度でサイト別の超微細構造を求めて,物性の起源をより深く知ることができる。
