在高质量的CePt 3Si单晶上进行比热测量。在超导转变温度Tc=0.46K和反铁磁转变温度TN=2.25K处的峰与我们以前的数据相比表明了急剧的转变。在0.3K以下，比热随温度的变化可用Cs/T=γs+βsT方程描述，其中γs=34.1mJ/K2 mol，βs= 1294 mJ/K3 mol，证明了超导带隙中存在线节点。
Specific heat measurements were performed on a high-quality single crystal of CePt3Si. Peaks at the superconducting transition temperature Tc=0.46K and the antiferromagnetic transition temperature TN=2.25K indicate sharp transitions compared to our previous data. The temperature dependence of specific heat below 0.3K is well described by the equation of Cs/T=γs+βsT with γs=34.1mJ/K2mol and βs=1294mJ/K3mol, evidencing line nodes in the superconducting gap.
