Description

The magnetic field induced broadening of the normal to superconducting resistive transition of YBa2Cu3O7/sub -//sub x/ thin films laser deposited on (100) MgO substrates for field oriented parallel to the c axis is found to be significantly reduced in comparison with that found previously in single crystals and in films deposited on SrTiO3. This reduction in broadening is associated with a high density of defects which, while causing a slight decrease in T/sub c/ and an increase in the zero-field transition width, seems to provide strong vortex pinning centers that reduce flux creep
