Combined spin-mass vortex with soliton tail superfluid 3He-B

We have observed spin-mass vortices (SMV) in superfluid 3B. The SMV is a combined topological object made up of a vortex line with mass current and a disclination line with spin current. It is also a termination line of a planar defect, the so-called θ soliton. The SMVs are bound either as pairs or to the container wall by the soliton. They are nucleated when a rotating 3He sample cools slowly through the A→B phase transition. The identification of the SMV is based on the NMR signatures of the soliton.
