Current-carrying states in superconducting channels with nonhomogeneities

Current-carrying states in superconducting channels with nonhomogeneities The stability of a current-carrying normal state in a superconducting channel with nonhomogeneities is considered at T<Tc. A value of the current is found below which the normal state becomes absolutely unstable with respect to nucleation and growth of a superconducting domain. Furthermore, the superconducting state appearing near a nonhomogeneity characterized by a critical temperatureT c1 higher than the critical temperatureT c of the main material is studied for the case ofT>T c . http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Low Temperature Physics Springer Journals

Abstract

The stability of a current-carrying normal state in a superconducting channel with nonhomogeneities is considered at T<Tc. A value of the current is found below which the normal state becomes absolutely unstable with respect to nucleation and growth of a superconducting domain. Furthermore, the superconducting state appearing near a nonhomogeneity characterized by a critical temperatureT c1 higher than the critical temperatureT c of the main material is studied for the case ofT>T c .
