摘要：

The heavy-fermion superconductor URu2Si2 orders antiferromagnetically at a Neel temperature T(N) higher than its superconducting transition temperature T(c). We develop a BCS-like theory for superconductivity occurring in the presence of an antiferromagnetic ground state (T(N) greater than or T(c)), and compare its predictions with very low temperature measurements of the specific heat in URu2Si2. The good quantitative agreement obtained shows that the AF ground state is a key factor in the comprehension of the unusual superconducting properties of this compound.
