Inducing exchange bias in La0.67Sr0.33MnO3−δ/SrTiO3 thin films by strain and oxygen deficiency
We present an exchange bias (EB) effect of variable size in La0.67Sr0.33MnO3−δ single and La0.67Sr0.33MnO3−δ/SrTiO3 (LSMO/STO) bilayers grown on STO substrates. Samples have been prepared by pulsed laser deposition (PLD) and high-pressure sputter deposition (HSD) in oxygen atmosphere at different oxygen pressures. Increased out-of-plane lattice parameters of the LSMO layers and reduced Curie te...
متن کاملStrain-Engineered Oxygen Vacancies in CaMnO3 Thin Films.
We demonstrate a novel pathway to control and stabilize oxygen vacancies in complex transition-metal oxide thin films. Using atomic layer-by-layer pulsed laser deposition (PLD) from two separate targets, we synthesize high-quality single-crystalline CaMnO3 films with systematically varying oxygen vacancy defect formation energies as controlled by coherent tensile strain. The systematic increase...
متن کاملOxygen-driven anisotropic transport in ultra-thin manganite films
Transition metal oxides have a range of unique properties due to coupling of charge, spin, orbital and lattice degrees of freedom and nearly degenerate multiple ground states. These properties make them interesting for applications and for fundamental investigations. Here we report a new phase with abnormal transport anisotropy in La(0.7)Sr(0.3)MnO3 ultra-thin films under large tensile strain. ...
متن کاملOxygen Deficiency in Plants
Plants, under natural or experimental conditions, can be subject to a range of O 2 concentrations from normal (normoxia) through deficient (hypoxia) to total absence (anoxia). Many metabolic processes are affected by O 2 deficiency but the most studied events are those related to respiration and metabolism of N. In the absence of a terminal electron acceptor for the electron transport chain, th...
متن کاملOxygen-deficiency-activated anomalous transport in La2/3Sr1/3MnO3−δ thin films deposited by laser ablation
The transport in oxygen-deficient polycrystalline La2/3Sr1/3MnO3−δ thin films deposited on Si(111) substrates using laser ablation is studied by measuring the resistivity and ac magnetic susceptibility over the range 2–300 K. The oxygen deficiency results in a serious shift of the insulating–metal (IM) transition toward the low-temperature side and anomalous transport behaviour over the low-tem...
