Abstract
The Nernst coefficient of displays two distinct anomalies in magnetic field. The feature detected at is similar to what is observed in at where a metamagnetic transition occurs. In , 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 is revised.
