Abstract

Thermodynamic data near the superconducting Tc on several different single-crystal specimens of the heavy-fermion system URu2Si2 are presented. Multiple-peak structure and narrow transition widths (Tc/Tc=0.05) are observed in the specific heat of the highest-quality samples. By carefully sectioning one of the crystals, it is shown that these peaks occur in macroscopically different parts of the crystal, and not as a result of vector superconductivity. Implications for the multiple-peak structure in UPt3 are discussed.
