摘要
The low-temperature specific heat of single-crystal samples of superconducting MgCNi3 with typical dimensions 200 mu m were measured for the first time. A computer controlled ac micro calorimeter using an optical fiber and an infrared light-emitting diode as the heat source was used down to 2 K at magnetic fields.up to 8 T. The specific heat data suggest a moderate coupling in MgCNi3.
