Spin dynamics at the dipole unlocking transition in {sup 3}He-A
- Univ. of Manchester (United Kingdom)
The equations describing the spin dynamics of {sup 3}He-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}{sub L} {plus_minus} {omega}{sub LD}), where {omega}{sub L} is the Larmor frequency and {omega}{sub LD} the Larmor frequency at the dipole unlocking field. Progress in searching for this mode experimentally is reported.
