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).
