Frustration by competing interactions in the highly-distorted double perovskites La2NaB'O6 (B' = Ru, Os)

open access: yes, 2012
The usual classical behaviour of S = 3/2, B-site ordered double perovskites generally results in simple, commensurate magnetic ground states. In contrast, heat capacity and neutron powder diffraction measurements for the S = 3/2 systems La2NaB'O6 (B ...

Electronic structure of the double perovskite Ba2Er(Nb,Sb)O 6 [PDF]

open access: yes, 2014
In this work, we present a detailed study of the structural and the electronic structure of the double perovskite Ba2Er(Nb,Sb)O 6. All calculations were performed with the Full-Potential Linear Augmented Plane Wave method (FP-LAPW) based on the Density ...

A Review of Synthesis, Characterization, Properties, and Applications of Double Perovskite Oxides

open access: yesInorganics
Double perovskites are represented by the formula A2BB’O6 and AA’BB’O6. These materials have been synthesized using the solid-state reaction, sol–gel, Pechini, and hydrothermal methods.

Lead-Free Halide Double Perovskites: A Review of the Structural, Optical, and Stability Properties as Well as Their Viability to Replace Lead Halide Perovskites

open access: yesMetals, 2018
Perovskite solar cells employ lead halide perovskite materials as light absorbers. These perovskite materials have shown exceptional optoelectronic properties, making perovskite solar cells a fast-growing solar technology.

ERRATUM: Revisiting Duffy's model for Sb3+ and Bi3+ in double halide perovskites: Emergence of a descriptor for machine learning

open access: yesOptical Materials: X, 2021
The Duffy's model is reformulated for Sb 3+ and Bi 3+ in cubic chloro- and bromoelpasolites with « 0D » perovskite structure. The new equation allows calculating the energy of the first s 2 → s 1 p 1 electron transition from crystal structure data.

Optimized Effective Potential Model for the Double Perovskites Sr2-xYxVMoO6 and Sr2-xYxVTcO6

open access: yes, 2011
In attempt to explore half-metallic properties of the double perovskites Sr2-xYxVMoO6 and Sr2-xYxVTcO6, we construct an effective low-energy model, which describes the behavior of the t2g-states of these compounds.

Magnetic moments of W 5d in Ca2CrWO6 and Sr2CrWO6 double perovskites

open access: yes, 2005
We have investigated the magnetic moment of the W ion in the ferrimagnetic double perovskites Sr2CrWO6 and Ca2CrWO6 by X-ray magnetic circular dichroism (XMCD) at the W L(2,3) edges.

Identification of Free and Bound Exciton States and Their Phase-Dependent Trapping Behavior in Lead Halide Perovskites

open access: yes, 2017
In this work we probe the sub-gap energy states within polycrystalline and single crystal lead halide perovskites to better understand their intrinsic photophysics behaviors.
