Abstract

To improve J_C properties in a magnetic field (J_C-B) of YBa₂Cu₃O_7-δ(YBCO) films by a TFA-MOD (trifluoroacetates metal organic deposition) method, we fabricated YBCO films with SnO₂-doping as artificial pinning centers and investigated the superconducting properties and the crystalline structures. TFA-MOD is expected as a cost-effective method with a non-vacuum system to fabricate YBCO films with high superconducting properties. However, YBCO films have problems that J_C decreases in a magnetic field (B). In this study, the TFA solutions with SnO₂ for pinning centers were used as starting materials. In the transmission electron microscope image, existence of second phase particles with size of 20-30 nm has been observed in the YBCO film. These nano-particles contained Sn-element and distributed randomly in the film. The J_C/J_C (self field) values of the SnO₂-doped YBCO films were enhanced in all magnetic field angles. Therefore it is considered that 3D pinning centers of Sn-compounds were introduced into YBCO film.
