Abstract

The equations describing the spin dynamics of He-3-A have been generalised to allow for the effect of susceptibility anisotropy on the Leggett-Takagi damping. Analytical and numerical solutions have been obtained for the configuration where 1 is locked parallel to a static magnetic field by boundaries. Our investigations show that the dipole unlocking transition, where d flips from parallel to perpendicular to 1, should proceed via a long lived spin precession at a frequency (omega(L) + omega(LD)), where omega(L) is the Larmor frequency and omega(LD) the Larmor frequency at the dipole unlocking field. Progress in searching for this mode experimentally is reported.
