A large electrocaloric effect is reported in a strain-engineered Ba0.85Ca0.15Ti0.9Zr0.1O3 (BCZT) thin film heterostructure driven by the near room-temperature electro-structural phase transition. An epitaxial BCZT/La0.7Sr0.3MnO3 (BCZT/LSMO) was grown on single-crystal SrTiO3 (100) substrate using pulsed laser deposition. In-depth x-ray diffraction and spectroscopic analyses revealed single-crys...

We report on the use of scanning force microscopy as a versatile tool for the electrical characterization of nanoscale memristors fabricated on ultrathin La(0.7)Sr(0.3)MnO(3) (LSMO) films. Combining conventional conductive imaging and nanoscale lithography, reversible switching between low-resistive (ON) and high-resistive (OFF) states was locally achieved by applying voltages within the range ...

Ž . Ž . The low-field magnetoresistance LFMR of oxygen-deficient La Sr MnO LSMO thin films deposited by laser 0.5 0.5 3 ablation under various oxygen pressures is studied with characterization of the microstructural, electroand magneto-transŽ . port properties in relation to oxygen vacancies, and explained by the spin-polarized tunneling SPT model. Significant oxygen deficiency dependence of th...
