Abstract

The thermal expansion of the single crystal of UPt3 has been measured at temperatures down to I mK by a capacitance dilatometer. We have first observed a large thermhl expansion anomaly around Ta=17mK. It corresponds to the specific heat anomaly observed in 1992. Furthermore, the expansion coefficients depend on T-2 at the temperature above Ta, and T2 at that below Ta respectively.
