我们用助熔剂法成功地生长了Ce（2）Coln（8）单晶。比热和电阻率的测量结果表明，Ce（2）Coln（8）在0.4K以下是重费米子超导体，其电子比热系数γ高达500 mJ/K（2）mol-Ce。
We succeeded in growing a single crystal of Ce(2)Coln(8) by the flux method. The results of specific heat and electrical resistivity measurements indicate that Ce(2)Coln(8) is a heavy-fermion superconductor below 0.4 K with an electronic specific heat coefficient gamma as large as 500 mJ/K(2)mol-Ce.
