Abstract

Electrical-resistivity measurements (T,H) on single-crystal URu2Si2 have been performed between 0.3 and 300 K in fields up to 7 T. (T) is highly anisotropic with the 300-K values parallel to the a and c axes differing by a factor of 2. Both directions exhibit a d/dT<0 down to 80 K, followed by a steep decrease in below 50 K. An upper antiferromagnetic transition is clearly discerned by a Cr-like anomaly at 17 K which also marks the onset of a strong, positive (H). Below 4 K (T) is isotropic and goes to zero at the superconducting transition Tc=0.8 K.
