摘要：

We present specific heat data for the heavy fermion superconductor CeCoIn5 close to the upper critical field H-c2 for magnetic fields applied along the [100] crystallographic axis. For fields above 10 T, the superconducting phase transition becomes first-order. In the same field range, we observe a second specific heat anomaly within the superconducting state, which we attribute to a Fulde-Ferrell-Larkin-Ovchinnikov state. (C) 2004 Elsevier B.V.
