Spiral instability of a longitudinal magnetic vortex in a thin, current-carrying superconducting film
Genenko Yu. A.
The left-handed spiral instability of a linear vortex in a planar superconductor in a magnetic field oriented parallel to the transport current is investigated on the basis of an exact solution for a spiral Abrikosov magnetic vortex in a plate of a type-II superconductor. It is shown that the critical instability current in thin films is comparable to the experimentally observed values and can determine the resistive behavior in a wide range of fields. © 1995 American Institute of Physics.
