Metastable vortex in superfluid 3He-B
Volovik G. E. , Salomaa M. M.
A new vortex solution of the Ginzburg-Landau equations is derived. This new solution describes a single-quantum vortex with a fourfold symmetry axis. This vortex may explain an unusual metastable state which is observed in hysteretic processes. The physical properties of the vortex are discussed.
