Abstract The warmup rate of the165Ho-enhanced nuclear spins in a HoVO4 single crystal in contact with dilute3He is shown to be dominated by the Kapitza resistanceR K at low bath temperature (T b 〈100 mK). This result is obtained from an analysis of the NMR signal during the warmup, following a demagnetization which cools the sample to a temperature of about 5 mK. The temperature variation ofR K (∝T b〈 /−3 ) is consistent with the acoustic mismatch model, but the magnitude is 40 times smaller than the theoretical predictions for a solid-liquid interface. The spin-lattice relaxation is also estimated, and found to be in agreement with the results of other authors.
