Strain driven structural phase transformations in dysprosium doped BiFeO₃ ceramics

Abstract

Chemical strain effects arising from the large size mismatch between the two A-site cations results in a lowering of the symmetry from polar <italic>R</italic>3<italic>c</italic> to a polar <italic>Cc</italic> in Bi_0.95Dy_0.05FeO₃.
