摘要：

YBa2Cu3O7−x (YBCO) film was deposited on {001} SrTiO3 (STO) substrate by pulse laser deposition (PLD). The microstructure of YBCO and STO was analyzed by High resolution X-ray diffraction (HRXRD). The results showed that the YBCO film alignment was C-axis coexisting with about 1 vol.% a-axis, and the spreading of YBCO’s out-plane alignment is anisotropic inherited from STO’s. In addition, there was 90° 〈110〉 twin domain with in-plane distort angle ±0.85° distort angle in the film, which was caused by T-O phase transition.
