摘要
We present a detailed study of the activated flux flow behaviour of superconducting-insulating YBa2Cu3O7/PrBa2Cu3O7 (YBCO/PrBCO) superlattices, as observed in the tails of the resistive transitions in magnetic fields perpendicular to the ab-plane. We focus our work on the magnetic field dependence of the activation energy U. In the case of decoupled thin YBCO layers, we show that U has a logarithmic dependence in B rather than a power law behavior.
