Zhou, Qingdi; Saines, Paul J.; Sharma, N; Ting, Jimmy; Kennedy, Brendan James; Zhang, Z; Withers, Raymond; Wallwork, Kia


The synthesis and structures of the perovskites Ln1/3TaO 3 are described. As the size of the Ln cation is reduced, the compounds display a sequence of structure: P4/mmm/La → Cmmm/Ce-Gd → Pmma/Tb, Dy → Pmc21/Ho, Er. Although apparently tetragonal in
