Abstract

The specific heat of a superconductor carries crucial signatures of its order parameter. The newly discovered superconductor MgCNi₃ is predicted to be unstable to ferromagnetism, and the symmetry of its order parameter symmetry is of current interest. To shed light on this issue, we have measured the low-temperature specific heat of MgCNi₃ in H. Careful analysis of the data suggests that γ(H) ∝ H. Together with other physical properties, the results imply that MgCNi₃ is a moderate-coupling BCS superconductor.
