“…Experimental Details A high-pressure dc sputtering technique, described in detail elsewhere [3] was used for the deposition of the YBCO films. For the Ag-doped films YBCO targets doped with 5 to 20 wt% of Ag have been used.…”

“…In order to obtain SYSO samples with more ordering degree when compared with the bulk samples, we produce films of this material on conventional SrTiO 3 (STO) single-crystals. There are experimental evidences that the substrate material improves some the characteristics of the high temperature superconducting thin films [3]; for this reason we grow YBa 2 Cu 3 O 7−δ (YBCO) superconducting films on SYSO novel material substrates in the film form.…”

“…10,11 For HBCO films we used pure oxygen at 3.3 mbar of pressure as sputtering gas. Deposition temperatures ranged between 880 • C and 900 • C. The films were annealed for 5 min in full oxygen after deposition at 550 • C. For BSCCO films we used 3.5 mbar of oxygen pressure at a substrate temperature of 910 • C. The films were annealed for 30 min in the same deposition conditions, and postannealed during 45 min using a pressure of 1 × 10 −2 mbar at 700 • C. The typical thickness of both kinds of films was between 100 and 300 nm.…”

“…More detailed information about the high quality of the superconducting and structural properties of our samples has been reported elsewhere. [9][10][11][12] The AFM technique operated in air was used to analyze the film morphology. The atomic force microscope is an AutoProbe PC AFM from Park Scientific Instruments.…”
