✦ Synopsis

The equations of motion, including dissipation, for the dynamic magnetism 3 of He-B following the complete turnoff of a small field are solved with the aim of demonstrating that two characteristic relaxation times may be distinguished. These are the rapid relaxation toward a rather long-lived mode (that turns out to involve an extremely simple motion), and the relaxation of this mode. The linear relaxation of the inverse frequency squared observed for the "wall-pinned mode" is rigorously justified, and corrections to the ideal case are discussed.

First we determine the 4 • matrix" Green's function for a p-wave pairing superfluid in a magnetic field where the order parameter is given by a real 3 x 3 matrix. For the B phase we take an order parameter which is equal to A i times a 3 • 3 matrix, yielding a rotation of angle 0 about the z-axis an
