The Nernst coefficient of CeCoIn5 displays two distinct anomalies in magnetic field. The feature detected at HK∼23T is similar to what is observed in CeRu2Si2 at Hm=7.8T where a metamagnetic transition occurs. In CeCoIn5, new frequencies are observed in de Haas-van Alphen oscillations when the field exceeds 23 T where the Dingle temperature decreases by about 30%. Based on the Nernst coefficient anomalies, the magnetic phase diagram of CeCoIn5 is revised.
