    Abstract

    YBa2Cu3O7-x+BaSnO3 (YBCO+BSO) mixed films with increasing BSO content were prepared on SrTiO3 substrates by pulsed laser deposition from YBCO+xwt% BSO mixed targets (x = 2, 3, 4, 5, 6, 8 and 9wt%). Transmission electron microscopy (TEM) images reveal that BSO is incorporated into the YBCO matrix in form of nanorods, whose density and size increase with increasing BSO content. The pinning properties for the mixed YBCO+BSO film were systematically studied. The 4wt% sample presents the maximum global pinning forces FP at all considered temperatures: 28.3GNm-3 near 2T at 77K, 103GNm-3 near 5T at 65K, and>241GNm-3 near 9 T at 40K.
