Description
YBa2Cu3O7-x+BaSnO3 (YBCO + BSO) mixed films with increasing BSO content were prepared on SrTiO3 substrates by pulsed laser deposition from YBCO+x wt% BSO mixed targets (x = 2, 3, 4, 5, 6, 8 and 9 wt%). 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 4 wt% sample presents the maximum global pinning forces FP at all considered temperatures: 28.3 GN m-3 near 2 T at 77 K, 103 GN m-3 near 5 T at 65 K, and>241 GN m-3 near 9 T at 40 K.
