We investigate the effect of partial substitution of Y by Ca in YBCO superconducting thin films. The films were grown on (100) SrTiO3single crystal substrates by pulsed laser deposition (PLD). The Ca doped film were ablated from Y1-xCaxBa2Cu3O7-δtargets with x=0, 0.05, 0.07, and 0.10. The dc transport properties of the films in applied magnetic field are analyzed to study the role of Ca on the superconducting properties of YBCO films. The irreversibility line for the samples with x=0 and 5 at.% Ca was derived from the E-J curves using a scaling theory for the vortex-glass transition. © 2003 Elsevier B.V. All rights reserved.
