Abstract
The Hall effect of a UPt3 single crystal has been determined for temperatures from 2-300 K. The total Hall signal is decomposed into the normal and anomalous parts. The anomalous part is very large and positive with a pronounced maximum near 30 K reaching 2.8×10−3 cm3 (A s)−1. The normal part is smaller and negative and corresponds in a one-band model to about one electron per formula unit. The change of sign of the temperature derivative of the anomalous Hall effect is related to the transition into the heavy-fermion state.
