ABSTRACT
The influence ofoxygen partial pressure on phase formation and magnetic properties of LSMO(La2/3 Sr1/3MnO3) thin films deposited on STO (1 1 1) substrates by pulsed laser deposition was investigated. Phase formation and epitaxial growth were confirmed by X-ray diffraction.Good crystalline mosaic is observed for oxygen partial pressures ranging from 0.3 to1.0m bar. For each of the pressures,the lattice parameters were estimated as suming the lattice distortion is volume conserving.The Curie temperatures TC vs lattice strain relation thus obtained is comparable to the available data in literature.Variation in coercive field ofthe films can be accounted for by the variationin TC.
