Structural principles of cation ordering and octahedral tilting in A-site ordered double perovskites: ferroelectric CaMnTi<sub>2</sub>O<sub>6</sub> as a model system
Elisabeth K. Albrecht, Antti J. Karttunen
Abstract
. The energy differences between various hypothetical double perovskite structures could be explained by studying their structural characteristics in detail. The relative energies are closely correlated with the Mn-O distances and Mn coordination in the studied structures.
