Impacts of cation ordering on bandgap dispersion of double perovskites
APL Materials, 2018 Double perovskites using dual metal cations are promising candidates for Pb-free perovskites. This study shows that the electronic structures of double perovskites (A2B+B3+X6) can be significantly modulated by cation ordering changes.

Double Double Cation Order in the High‐Pressure Perovskites MnRMnSbO6 [PDF]
Angewandte Chemie International Edition, 2016 AbstractCation ordering in ABO3 perovskites adds to their chemical variety and can lead to properties such as ferrimagnetism and magnetoresistance in Sr2FeMoO6. Through high‐pressure and high‐temperature synthesis, a new type of “double double perovskite” structure has been discovered in the family MnRMnSbO6 (R=La, Pr, Nd, Sm).
