Abstract
We report on the epitaxial growth of magnetoresistive La0.7Ca0.3MnO3 and La0.7Sr0.3MnO3 thin films by chemical solution deposition. Thin films were prepared by spin-coating of single-crystal LaAlO3 (100) substrates with precursor solutions of different concentrations and crystallized at 850°C. The structure of the thin film was found to be influenced by the concentration of the spin-coating solution. The thin film structure and epitaxy was clearly improved by reducing the concentration of the precursor solution. All thin films displayed excellent electrical properties such as a low resistivity and very high metal-insulator transition temperatures T MI .
