Cation ordering in distorted perovskites (MLa)(MgTe)O6, M = Na, K
Abstract
The synthesis and crystal structure of the pseudo-orthorhombic (a≈b≈√2a0, c≈2a0) ordered perovskite MLaMgTeO6(M = Na and K) are reported. X-ray, electron and neutron diffraction and microscopy established that both compounds have a perovskite structure with ordering in the A and B sublattices.
