- 論文の詳細を見る
We have studied the local crystal structure of a multiferroic system BiMnO_3 by means of atomic pair distibution function (PDF) analysis on neutron powder diffraction data. The domains with space group P2 or P2_1 whose atomic shifts break a symmetry of C-center exist in the bulk BiMnO_3 with a space group C2, which is consistent with recent results of electron diffraction. The domain size is larger than 100A, also estimated by the PDF analysis. Because domains which have atomic shifts with different directions, typically the opposite direction, also exist, the bulk material "apparently" has a space group C2.
