Dang, P. Mikheenko, A. Sarkar, M. AwangKechik, J. Abell, P. Paturi, H. Huhtinen, A. Crisan] The combination of two methods: Ag substrate decoration and introduction of BZO nano-inclusions has been used in a pulsed laser deposition (PLD) method to increase the critical density (J c) of YBCO films. The films were deposited on single crystal SrTiO3 (STO) substrates decorated with various architecture of Ag nano-dots. We have studied the diameter and density of Ag nano-dots and their influence on J c of BZO-added YBCO films. We found that 15 laser pulses on the Ag target gives an optimum result in increasing J c in comparison with BZO-doped YBCO films of the same thickness in self-field and low applied magnetic fields. A higher number of laser pulses on the Ag target led to increasing critical current density in high applied magnetic fields only (above 2T). We have studied films of the thickness from 0.4μm to 3.8μm and found that the highest J c at all applied fields investigated is achieved for a 1.2μm thick film. The transmission electron microscopy clearly shows BZO nano-rods that provide strong c-axis pinning centres in the films.
