Growth and superconducting properties of Sm1Ba2Cu3O7-delta thin films

We successfully used the pulsed laser ablation and deposition to prepare su perconducting thin films of SmBaCuO under different growth parameters. The films were grown on both MgO (100) and SrTiO3 (100) substrates. The best sa mples showed a good degree of orientation; having the theta-scan around the 005 reflection an FWHM approximate to 0.2 degrees. We report the critical temperature as a function of the deposition parameters, comparing the resul ts between the two substrates. We also estimate the critical current densit y at 60K from the magnetization curve.
