  • NMR Experiments on Rotating Superfluid 3He-A : Evidence for Vorticity
    (1982) Hakonen, Pertti J.; Ikkala, Olli T.; Islander, S. T.; Lounasmaa, O. V.; Markkula, T. K.; Roubeau, P.; Saloheimo, K. M.; Volovik, G. E.; Andronikashvili, E. L.; Garibashvili, D. I.; Tsakadze, J. S.

    Experiments on rotating superfluid 3He-A in an open cylindrical geometry show a change in the NMR line shape as a result of rotation: The amplitude of the peak decreases in proportion to f(T)g(Ω), where Ω is the angular velocity of rotation; at the same time the line broadens. Near Tc, f(T) is a linear function of 1−T/Tc. At small velocities g(Ω)∝Ω. These observations are consistent with the existence of vortices in rotating 3He-A.
