摘要：

We have realized highly epitaxial La0.7Ca0.3MnO3/YBa2CU3O7-x/La0.7Ca0.3MnO3 (LCMO/YBCO/LCMO) trilayers grown on SrTiO3 (001) oriented single crystal substrates by dc sputtering technique. Transport and magnetic measurements indicate that the superconducting critical temperature is strongly suppressed while the Curie temperature is higher than in a single LCMO film. These results are discussed in terms of interaction between superconductivity and magnetism and strain relaxation of the LCMO layer.
