✦ Synopsis

We measured the Kapitza resistance between TyV04 and liquid 3He in the temperature range 1-IOmK. The Kapitza resistance was proportional to T below about 3mK. We also observed the decreasing Kapitza resistance between HoV04 and liquid 3He with decreasing temperature, but its value was two orders of magnitude smaller than that for TmV04. The experimental results can be qualitatively explained by th magnetic coupling between enhanced nuclear spins of Tm or Ho and nuclear spins of adsorbed solid 9 He on the surface of the crystal.
