The Kapitza resistance between TmVO{sub 4} and liquid {sup 3}He in the temperature range 1-40 mK was measured. The Kapitza resistance was proportional to T{sup 2} below about 3 mK. By adding a small amount of {sup 4}He, the Kapitza resistance was enlarged. Applying magnetic fields up to about 70 Oe, the resistance also increased. The decreasing Kapitza resistivity with decreasing temperature was also observed between HoVO{sub 4} and liquid {sup 3}He. Its value, however, was two orders of magnitude smaller than that for TmVO{sub 4}. The experimental results can be explained by the magnetic coupling between enhanced nuclear spins of Tm or Ho and nuclear spins of adsorbed solid {sup 3}He on the surface of the crystal. By using this model numerical calculation of the Kapitza resistivity was made.
