Double Double to Double Perovskite Transformations in Quaternary Manganese Oxides [PDF]

Angewandte Chemie International Edition, 2021
AbstractControl of cation ordering in ABX3 perovskites is important to structural, physical and chemical properties. Here we show that thermal transformations of AA′BB′O6 double double perovskites, where both A and B sites have 1:1 cation order, to (A0.5A′0.5)2BB′O6 double perovskites with fully disordered A/A′ cations can be achieved under pressure in

Layered Double Perovskites [PDF]

Annual Review of Materials Research, 2021
Successful strategies for the design of crystalline materials with useful function are frequently based on the systematic tuning of chemical composition within a given structural family. Perovskites with the formula ABX3, perhaps the best-known example of such a family, have a vast range of elements on A, B, and X sites, which are associated with a ...

CaFeFeNbO₆ – an iron-based double double perovskite [PDF]

Chemical Communications, 2023
CaFeFeNbO6, synthesised at 14 GPa pressure, is the first reported Fe-based double double perovskite. Fe/Nb disorder leads to a spin glass ground state below a freezing transition at 12 K.

Double and double double perovskites in the RMnMnTaO6 series [PDF]

Journal of Solid State Chemistry, 2022
A new family of perovskites RMnMnTaO6 has been synthesised at high pressure for representative R ​= ​La, Nd, Sm, Eu, Gd, Y and Lu that span the whole rare earth series. The structure type changes from tetragonal P42/n double double perovskite (DDPv) type with columnar R3+/Mn2+ cation order (R ​= ​La, Nd, Sm) to monoclinic P21/n double perovskite (DPv) (
