  • Abstract
    Perovskite manganite thin films of La0.5Ca0.5MnO3 doped with 5% Fe or Ni were grown on SrTiO3, LaAlO3, NdGaO3, and Si single-crystal substrates by pulsed-laser deposition (PLD). 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 on these films correlate with their structural, magnetoresistance, and electronic properties.
