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 T_a=17mK. It corresponds to the specific heat anomaly observed in 1992. Furthermore, the expansion coefficients depend on T^-2 at the temperature above T_a, and T² at that below T_a respectively.
