Temperature dependence of the Leggett-Takagi relaxation time and spin diffusion coefficient in3He-B for 6 bar

We have applied the homogeneously precessing domain (HPD)—one of excited quantum states of3He-B with coherent precessing—for studying the magnetic relaxation processes down to 0.3T c . The power absorbed by HPD from CW NMR field is divided into several contributions corresponding to different relaxation processes. We have studied the nonhydrodynamic correction of the spin diffusion and the Leggett-Takagi (L-T) relaxation.
