Emergence of Dissipative Structures in Current-Carrying Superconducting Wires (POSTPRINT)

摘要

We discuss the emergence of a spontaneous temperature and critical current spatial modulation in current carrying high-temperature superconducting wire. The modulation of the critical current along the wire on a scale of 3-10 mm forces a fraction of the transport current to crisscross the resistive interface between the superconducting film and normal metal stabilizer attached to it. This generates additional heat that allows such a structure to be self- sustainable. Stability and the conditions for experimental observation of this phenomenon are also discussed.
