Abstract
Using pulsed laser deposition method, the heavy double-doped La1/3(Ca2/3Sr1/3)2/3MnO3 (LCSMO) thin film was epitaxially prepared on LaAlO3 (0Â 1Â 2) single crystal substrate. The structure and transport properties of the film were investigated. The results indicate that the film is perovskite pseudocubic structure, and the surface is relatively smooth. The electrical transport property of the film was determined using the DC four-probe method. The results exhibit semiconducting behavior, and no metal-insulator transition temperature TMI of the film in the temperature range of 77-400Â K. This character was explained by the MnO6 octahedron, which is distorted with heavy concentration.
