Lead‐Free Double Perovskites for Perovskite Solar Cells
Solar RRL, 2019Perovskite solar cells (PSCs) have achieved a high power conversion efficiency (PCE) with a credible certified value over 25%. More efforts have been devoted to the development of stable and ecofriendly perovskite materials. Lead‐free double perovskites (LFDPs) are a noteworthy choice as a photoactive layer because of their favorable photovoltaic (PV ...

Magnetism in Double Perovskites
Journal of Superconductivity and Novel Magnetism, 2012Double-perovskite compounds with general formula ABB′O6, have attracted a lot of attention in recent years due to a variety of properties exhibited by them. In this paper, we will review our recent study on a number of double-perovskite compounds, namely La-doped Sr2FeMoO6, Cr-based family of compounds, Sr2CrXO6 (X=W, Re, Os), characterized with ...

Magnetism of the double perovskite Sr2FeMoO6
Journal of Magnetism and Magnetic Materials, 2003Abstract We have completed a systematic study of the magnetization of a single crystal of double perovskite Sr 2 FeMoO 6 over a wide range of temperatures and fields. Near the ordering temperature of 405.0 K, the magnetization is described by critical exponents β =0.50±0.03 and γ =1.20±0.03.

Yttrium-based Double Perovskite Nanorods for Electrocatalysis
ACS Applied Materials & Interfaces, 2022Herein, we investigate the effect of the chemical composition of double perovskite nanorods on their versatile electrocatalytic activity not only as supports for the oxidation of small organic molecules but also as catalysts for the oxygen evolution reaction. Specifically, Y2CoMnO6 and Y2NiMnO6 nanorods with average diameters of 300 nm were prepared by

Multiferroicity in double perovskite Y2CoMnO6
AIP Conference Proceedings, 2012We have synthesized the double perovskite Y2CoMnO6. The crystal structure is identified to be monoclinic (space group P21/n). We report detailed analysis of this material using XRD, magnetization, resistivity and dielectric constant measurements. A material from the same series, Lu2CoMnO6 has been reported to have E-type antiferromagnetic structure in ...

Magnetoresistance stories of double perovskites
Pramana, 2015Tunnelling magnetoresistance (TMR) in polycrystalline double perovskites has been an important research topic for more than a decade now, where the nature of the insulating tunnel barrier is the core issue of debate. Other than the nonmagnetic grain boundaries as conventional tunnel barriers, intragrain magnetic antiphase boundaries (APB) as well as ...

Ba2PrPtO6: A novel double perovskite
Journal of Solid State Chemistry, 1992The structure of the Ba 2 PrPtO 6 compound has been determined by X-ray powder diffraction and profile analysis and has been confirmed by TEM and HREM. The structure of this material is made up of alternating [PtO 6 ] and [PrO 6 ] octahedra along the three a, b , and c directions. Magnetic properties are also presented and discussed.

ESR of double-perovskite Sr2FeMoO6
Physica B: Condensed Matter, 2002Abstract We present an ESR study of Sr 2 FeMoO 6 in the paramagnetic region. A single line at g ≈2 was associated with Fe 3+ ions. The intensity follows Curie–Weiss law in the whole T range. For T >500 K a secondary line is attributed to ferromagnetic (FM) impurities.
