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) (

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.

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 ...

Halide Double Perovskite Ferroelectrics

Angewandte Chemie, 2020
AbstractHalide double perovskites have recently emerged as a promising environmentally friendly optoelectronic and photovoltaic material for their inherent thermodynamic stability, high defect tolerance, and appropriate band gaps. However, to date, no ferroelectric material based on halide double perovskites has been discovered.

Bi-based halide perovskites: Stability and opportunities in the photocatalytic approach for hydrogen evolution

Catalysis Communications, 2023
In this study, we successfully prepared Bi-based single perovskites of the A3Bi2I9 type (A = Cs, Rb, MA, FA), and, for the first time, attempted to experimentally obtain double perovskites Cs2B'BiI6 type (B′ = Ag, Au, In, Cu).
