Magnetic 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...
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 کاملInterfacial magnetism in manganite superlattices
We use a two-orbital double-exchange model including superexchange interactions, Jahn-Teller lattice distortions, and long-range Coulomb interactions to investigate the origin of magnetically disordered interfaces between ferromagnetic metallic (FM) and antiferromagnetic insulating (AFI) manganites in FM/AFI superlattices. The induced magnetic moment in the AFI layer varies nonmonotonically wit...
متن کاملسنتز نانو بلورکهای lsm (lanthanum strontium manganite) به منظور استفاده درکاتدپیل سوختی اکسید جامد
در این پژوهش سنتز نانو بلورک های lsm (lanthanum strontium manganite) به منظور استفاده درکاتد پیل سوختی اکسید جامد به روش هم رسوبی مورد بررسی قرار گرفته است. اکسید لانتانیوم (la2o3)، کربنات استرانسیوم (srco3) و کربنات منگنز آبدار (mnco3.xh2o) به عنوان ماده اولیه انتخاب گردیده است. برای ایجاد محلول های نیترات لانتانیوم، نیترات استرانسیوم و نیترات منگنز، مقادیر توزین شده اولیه در اسید نیتریک غلیظ ...
15 صفحه اولElectronic and magnetic reconstructions in manganite superlattices
We investigate the electronic reconstruction at the interface between ferromagnetic metallic (FM) and antiferromagnetic insulating (AFI) manganites in superlattices using a two-orbital double-exchange model including superexchange interactions, Jahn-Teller lattice distortions, and long-range Coulomb interactions. The magnetic and transport properties critically depend on the thickness of the AF...
