Abstract

The angular dependence of the critical current density Jcwas analyzed in Y0.9Ca0.1Ba2Cu3O7-δepitaxial thin films grown by PLD technique on SrTiO3and CeO2buffered Al2O3substrates. The latter shows a broad peak in theJcvs θ curves at θ=0° (H // c), revealing a directional character of the pinning mechanisms. This feature is affected both by temperature and magnetic field intensity emerging at intermediate T and H values. The origin of the c-axis correlated pinning is discussed and compared with the previously reported studies on the directional pinning. © 2006 American Institute of Physics.
