摘要：

Thermodynamic data near the superconducting T(c) on several different single-crystal specimens of the heavy-fermion system URu2Si2 are presented. Multiple-peak structure and narrow transition widths (DELTA-T(c)/T(c) = 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.
