We report on the role of oxygen content alone on structural and transport properties of La0.65Sr0.35MnO3-delta (LSMO) thin films. Identical films were deposited side-by-side during a single deposition run and subsequently post-annealed separately in vacuum to systematically vary the oxygen content. All films remained coherently strained to the SrTiO3 substrate, with no broadening of rocking curve widths after post-anneal. As oxygen content decreases, the LSMO unit cell expands while the metal-insulator transition temperature T-MI decreases. A linear correlation between the out-of-plane lattice parameter and the metal-insulator transition temperature was observed. (C) 2012 American Institute of Physics. [doi:10.1063/1.3676268]
