โœฆ Synopsis

The flux dynamics in magnesium diboride films becomes altered by scattering resulting in an unprecedented quenching of flux motion that is beyond conventional vortex pinning. At currents approaching the pair-breaking value and magnetic fields approaching the uppercritical field, the conductance diverges and the current-resistance and temperature-conductance curves become parallel, showing mainly a shift in the transition due to pair-breaking with minimal signs of flux motion.

The field dependences of the critical current, current-voltage characteristics and a.c. susceptibility have been investigated for superconducting YBa2Cu307 films prepared by laser ablation. It was shown that the flux line pinning in polycrystalline high Tc films occurs due to anisotropy of the super
