Abstract
A detailed study on YBa2Cu3O7-6 (YBCO) films with BaZro3 (BZO) inclusions (YBCO-BZO) deposited on substrate with different BZO contents is presented. X ray diffraction, SEM imaging and superconductive critical temperature (Tc) measurements were performed to evaluate film growth quality. Independently from the BZO content, all YBCO-BZO films showed Tc values close to that of pure YBCO indicating that the Tc reduction which is usually observed on YBCO-BZO films can be successfully recovered by changing the deposition conditions. All YBCO-BZO films showed an improved critical current density (Jc) dependence on magnetic field if compared to the typical Jc(H) of YBCO, resulting in higher irrevers..
