Spin-mass vortex in He-3-B: Order-parameter texture and NMR signature - art. no. 094504

We have calculated numerically the change in the NMR signal of rotating sup erfluid He-3-B induced by the presence of one spin-mass vortex. The NMR lin e shape is determined from the equilibrium distribution of the order-parame ter axis (n) over cap (r). Depending on the external conditions, two textur es of different symmetry and with clearly distinguishable NMR behavior are obtained. One of these agrees with published NMR measurements, the other ha s not been reported earlier. The methods are discussed by which the texture transition and the new reflection-symmetric texture could be observed expe rimentally.
