Abstract
It is shown that a flux vortex, in the presence of a sufficiently large current density applied parallel to its axis, is unstable against the growth of helical perturbations. This instability, which has an analog in magnetohydrodynamics, may play a critical role in current-carrying type-II superconductors subjected to longitudinal magnetic fields.Keywords
