[摘要]：A single-step process to prepare epitaxial nanocomposite La0.7Sr0.3MnO3/La2O3 thin films formed by spontaneous phase separation using a chemical solution deposition is presented. High magnetic field and temperature dependences of magnetic, transport, and magneto-transport properties of the films were investigated. The relationship between the enhanced magnetoresistance and microstructure and chemical inhomogeneities of the films are discussed. (C) 2012 American Institute of Physics. [doi: 10.1063/1.3675461]
