Crystal structures and phase transitions in a-site deficient perovskites Ln1/3TaO3
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 P4/mmm, electron diffraction patterns of Tm1/3TaO3...
