| 中文摘要 | La0.7Ca0.3MnO3(LCMO)/Gd0.7Ca0.3MnO3(GCMO) multilayers have been prepared by pulsed laser deposition. High-resolution transmission electron micrographs demonstrate that perfect hetero-epitaxial growth has been achieved in the LCMO/GCMO superlattices with strains. In the superlattices, the resistivity-peak temperature decreases with reducing the thickness of the LCMO layers. Large low field magnetoresistance (LFMR) of Delta rho/rho(H) = 278% is obtained at 78.5 K in a LCMO/CCMO superlattice when a magnetic field swept within +/- 3100 Oe. This result suggests that the interface strains between LCMO and GCMO layers may have influences on the magnetic transport properties and a suitable film structure could be used to increase the LFMR.
