Abstract

YBa2Cu3O7-δthin films with BaZrO3(BZO) inclusions have been deposited on SrTiO3substrates in order to study the effect of nanoparticles addition into YBCO matrix. Samples with 7% (mol) BZO content were obtained by PLD varying the deposition conditions, in order to evaluate their effect on the films transport properties. The change in deposition parameters, especially of the deposition temperature, has been discovered to be efficient for a reduction or complete recovery of the critical temperature decrease produced by BZO addition. The effect of the deposition temperature on in-field films transport properties as well as on the presence of c-axis correlated defects typically ascribable to nanoparticles addition, can be recognised in an improvement in JCretention in applied magnetic field and, for higher temperatures, the appearance of correlated pinning contribution, as confirmed by pinning force density measurements. © 2009 Elsevier B.V.
