We investigate the effect of partial substitution of Y by Ca in YBCO superconducting thin films. The films were grown on (1 0 0) SrTiO 3 single crystal substrates by pulsed laser deposition (PLD). The Ca doped film were ablated from Y 1Γx Ca x Ba 2 Cu 3 O 7Γd targets with x ΒΌ 0, 0.05, 0.07, and 0.10
We have prepared thin films of YBCO on Si (100) and on Si with Ag-buffer layer by DC-magnetron sputtering. Post-deposition annealing at 7173K was necessary in order to obtain superconducting films. The films on silicon have no superconducting transition down to 50k. The films on silicon with Ag-buff
