Synthesis, structural characterization and magnetic properties of the series of double perovskites Ba1+xLa1−xMnSbO6with 0.1 ≤ x ≤ 0.7
(Elsevier Science Sa, 2017-05-15)
Double perovskites Ba1+xLa1−xMnSbO6were synthesized by traditional ceramic methods in air as polycrystalline powders. The 0.1 ≤ x ≤ 0.2 compounds belong to the I 2/m monoclinic space group, while the perovskites with x ≥ 0.3 ...
Structural characterization and electrochemical properties of (La,Sr)(Al,Mg)O 4−δ perovskites
(Royal Society of Chemistry, 2020-07)
LaSrAl1−xMgxO4−δ (x = 0.0?0.3) layered perovskites were synthesized by a nitrate?citrate route followed by annealing in air at 1100 °C, and studied as potential electrolyte materials in solid oxide fuel cells (SOFCs). The ...
Charge disproportionation and the pressure-induced insulator?metal transition in cubic perovskite PbCrO3
(National Academy of Sciences, 2014-12)
The perovskite PbCrO3 is an antiferromagnetic insulator. However, the fundamental interactions leading to the insulating state in this single-valent perovskite are unclear. Moreover, the origin of the unprecedented volume ...
Water insertion and combined interstitial-vacancy oxygen conduction in the layered perovskites La1.2Sr0.8−xBaxInO4+δ
(Royal Society of Chemistry, 2019-05)
Layered perovskites of K2NiF4-type consist of single octahedral sheets alternating with NaCl-type layers, containing a substantial interstitial space. Based on the parent LaSrInO4+δ oxide, the series of title compounds ...
Spin reorientation and metamagnetic transitions in R F e0.5 C r0.5 O3 perovskites (R=Tb, Dy, Ho, Er)
(American Physical Society, 2018-10)
In this work we present the magnetic structures and spin reorientation (SR) transitions of the mixed orthochromite-orthoferrite perovskites RFe0.5Cr0.5O3 (R=Tb, Dy, Ho, Er). Magnetization as a function of temperature and ...
Canted ferrimagnetism in the distorted double perovskite La3Mn2NbO9
(Elsevier Science SA, 2021-02)
The synthesis, structural characterization, and magnetic properties of La3Mn2NbO9 double perovskite are reported. The crystal structure has been refined by X-ray and neutron powder diffraction data in the monoclinic space ...
Raman and infrared spectroscopy of Sr2B′UO6 (B′ = Ni; Co) double perovskites
(Elsevier Science, 2010-11)
Temperature dependent normal modes and lattice thermal expansion of Sr 2B′UO6 (B′ = Ni, Co) double perovskites were investigated by Raman/infrared spectroscopies and synchrotron X-ray diffraction, respectively. Monoclinic ...

(Academic Press Inc Elsevier Science, 2012-10)
The synthesis, structural characterization, and magnetic properties of La 3Co 2SbO 9 double perovskite are reported. The crystal structure has been refined by X-ray and neutron powder diffraction data in the monoclinic ...
Electroluminescence transients and correlation with steady-state solar output in solution-prepared CH3NH3PbI3 perovskite solar cells using different contact materials
(IOP Publishing, 2020-01)
Electroluminescence (EL) transients of solution-prepared CH3NH3PbI3 perovskite solar cells were recorded under different biasing voltage conditions. The EL transients are reversible and show a sharp increase and a peak in ...
