摘要
The specific heat as a function of temperature between 1.4 and 10 K for fields between 28 and 45 T reveals a small anomaly in the C/T data that is first visible at 32 T. The anomaly grows in size monotonically up to our highest field of measurement (45 T); the temperature of the maximum of the specific heat anomaly grows as well with increasing field at approximately 0.21 K/T, up to a value of T-peak=4.1 K at 45 T. Thermodynamic considerations indicate that the field-induced transition is first order. The data are compared to the weak metamagnetic transition in the magnetization observed around 42 T by Takeuchi et al.
