DOIAbstract
The critical current density (Jc) and the nature of its temperature dependence is examined for the first time for the case of Fe doped epitaxial thin films of Y1Ba2Cu3O7-δ. These Jc systematics are analysed in terms of flux pinning at Twin boundary (TB) planes, tunneling across such planes and influence of magnetic impurities on superconducting gap parameter via Cooper pair breaking
