摘要

Structural investigations on double perovskites NaLaMgWO₆ using combined X-ray powder diffraction and transmission electron microscopy techniques have verified the obtained structure with a space group of C2/m (No. 12), which is different from the original report of the monoclinic one. In addition, high-angle annular-dark-field electron micrographs of the NaLaMgWO₆ double perovskite revealed the formation of antiphase boundaries, orientation domains and phase separation in Na_0.7La_1.1MgWO₆ and NaLaMg_1.3W_0.9O₆ by altering the compound chemistry. These results provide a direct structural insight to link the physical properties with their crystallographic defects for double perovskites on both scientific and engineering basis.
