摘要：
YBa2Cu3O7-x (YBCO) films were fabricated on LaAlO3 (LAO) substrate under various firing temperatures (760-870C) in the crystallization process by metalorganic deposition (MOD) method using trifluoroacetates. The effect of firing temperature on the structure and properties of YBCO films was systematically investigated. According to the XRD and SEM images, the films fired at low temperature (760-800C) showed poor electrical performance due to rough surfaces and impurity phases. However, the films fired at 850C showed the highest critical temperature of 90 K and the highest J (c) of 3.1 MA/cm2 which attribute to the formation of a purer YBCO phase, fewer pores, and stronger biaxial texture.
