摘要：

Epitaxial YBa2Cu3O7-x thin films with varying oxygen content have been studied by x-ray-diffraction (XRD) mapping. Results show that the films have a high epitaxial quality with the a and b axes aligned in the [100] or [010] directions of the (001) LaAlO3 substrate. The two twin domains in the orthorhombic films are present in equal amounts, both for the as-deposited and the oxygen-deficient films. From XRD maps of the (00l), (308), and (038) peaks, the a-, b-, and c-axis lengths were measured as a function of superconducting transition temperature T(c). The results show that the unit-cell variation for relaxed epitaxial films agrees with that of bulk material.
