Using Pulsed Laser Deposition (PLD) our team is able to fabricate and examine Yttrium-Barium-Copper-Oxide (YBCO) thin films of high quality. A particular point of investigation is the influence of an in situ pre-deposited gold film. While growing the superconducting film one can achieve a formation of gold nano clusters in an YBCO matrix through heating of the initial gold layer. We studied the temperature dependence of the resistance in respect to the YBCO film thickness for various gold layers. Furthermore the critical current density at 77 K and their temperature dependence will be compared with the one of non-modified YBCO thin film structures.
