摘要：

Epitaxial thin films of a copper-oxide-based isotropic metallic oxide (La8-xSrxCu8O20) and superconducting heterostructures (YBa2Cu3O7/La 8-xSrxCu8O20/YBa2Cu 3O7) have been fabricated by 90° off-axis sputtering. La8-xSrxCu8O20 is an oxygen-deficient pseudocubic perovskite that exhibits Pauli paramagnetism. X-ray diffraction and cross-sectional transmission electron microscopy reveal the heterostructures to have high crystalline quality and clean interfaces. This material will facilitate fabrication of ideal superconductor-normal-metal- superconductor Josephson junctions with low boundary resistance due to its excellent chemical compatibility and lattice match with cuprate superconductors and will be useful for determining the source of interface resistance in such heterostructures. © 1995 American Institute of Physics.
