摘要

Perovskite manganite thin films of La0.5Ca0.5MnO 3 doped with 5% Fe or Ni were grown on SrTiO3, LaAlO 3, and NdGaO3 single-crystal substrates by pulsed-laser deposition. The as deposited films were amorphous and epitaxial layers were obtained only after ex-situ post-annealing at 900 °C under 1 atmosphere of oxygen. The effects of different substrates and oxygen-annealing conditions of the films correlate with their structural, magnetoresistance, and electronic properties.
