On the spin dynamics of 3He-B at the minimum of spatially nonuniform external magnetic field

The spin dynamics of the superfluid B phase of 3He in a quadratic external magnetic field is investigated. The existence of a set of steady-state solutions of the equations of spin dynamics is demonstrated. These solutions describe coherently precessing spin patterns localised around the minimum of the external magnetic field. The set of solutions is noted for the fact that the higher the dephasing of a corresponding spin pattern and the shorter its characteristic length, the higher the angular velocity of spin precession is
