| In [[superconductivity]], a '''Josephson vortex''' (after [[Brian David Josephson|Brian Josephson]] from Cambridge University) is a vortex of [[supercurrent]] in a [[long Josephson junction]] (LJJ). The supercurrents circulate around the vortex center which is situated inside the Josephson barrier. In contrast to [[Abrikosov vortex|Abrikosov vortices]] in [[type-II superconductors]], a Josephson vortex has ''no normal core''.
| |
| | |
| Usually the Josephson vortex's supercurrents create a magnetic field with the total flux equal to <math>\Phi_0</math>—a [[magnetic flux quantum|single flux quantum]]. Such a vortex is therefore called a (Josephson) [[fluxon]]. It has been shown that under certain conditions a propagating Josephson vortex can initiate another Josephson vortex. This effect is called flux cloning (or fluxon cloning). Although a second vortex appears, this does not violate the conservation of the single flux quantum.
| |
| | |
| Recently{{When|date=February 2011}} it was demonstrated by Hilgenkamp et al. that Josephson vortices in the so-called [[0-π LJJ]] can also carry half of the [[magnetic flux quantum|flux quantum]], and are called [[semifluxon]]s.
