Abstract

The magnetic and transport properties of epitaxial La_0.7Sr _0.3MnO₃ (LSMO) thin films were investigated. The film thickness and the oxygen pressure dependent lattice strain was compared in the films. The ferromagnetic transition (T_C) and metal-insulator transition (T_MI) temperatures was supressed by the lattice strain induced by the oxygen pressure. The results show that the physical properties of the LSMO films is less sensitive to the film thickness and strongly depends on the oxygen content.
