Abstract

The compound URu₃ has been found to exhibit superconductivity below 0.15 K. Polycrystalline specimens of URu₃ and two other U‐compound superconductors, UPt₃ and UCo, have been investigated by means of ac magnetic susceptibility measurements in zero and finite magnetic fields. Electrical resistivity, dc magnetic susceptibility, and specific‐heat measurements on URu₃ and UCo reveal non‐heavy‐fermion behavior for both compounds and evidence for relatively large exchange enhancement of the Pauli paramagnetic susceptibility for UCo.
