Effect of Grinding Time on Structural and Thermal Properties of Strontium-Doped Nanostructural Lanthanum
In this work, the strontium-doped lanthanum manganite- a ceramic material- used as cathode in solid oxide fuel cells. An impression of grinding time on the structural and thermal properties of Sr-doped LaMnO3 system with La1-xSrxMnO3 (x=0.2) stoichiometric ratio was investigated. The nano crystallite LSM powder with cubic structure was prepared by varying the milling time of planetary monomill ...
متن کاملIntrinsic Mobility Limiting Mechanisms in Lanthanum-Doped Strontium Titanate
The temperature dependent Hall mobility data from La-doped SrTiO3 thin films are analyzed and modeled considering various electron scattering mechanisms. We find that a ∼6 meV transverse optical phonon deformation potential scattering mechanism is necessary to explain the dependence of transport on temperature between 10–200 K. Also, we find that the low temperature electron mobility in intrins...

متن کاملThermodynamic and kinetic assessments of strontium-doped lanthanum manganite perovskites for two-step thermochemical water splitting
Solar-driven thermochemical water splitting using non-stoichiometric oxides has emerged as an attractive technology for solar fuel production. The most widely considered oxide for this purpose is ceria, but the extreme temperatures required to achieve suitable levels of reduction introduce challenges in reactor design and operation, leading to efficiency penalties. Here, we provide a quantitati...
متن کاملMagnetic transitions and electrical transport in lanthanum strontium manganite: Effects of substitutions and high pressure
The observation of a substitution-induced ferromagnetic order ~Tc5200 K! is reported in antiferromagnetic La0.9Sr0.1MnO3 ~TN5130 K! when 0.05 of La is replaced by yttrium. Important results of ferromagnetic resonance ~FMR! and high-pressure transport studies are as follows. ~i! Data on FMR linewidth and resistivity provide evidence for the presence of microscopic magnetic inhomogeneities, possi...
