(a) Temperature dependent specific heat capacity without magnetic field. Black circles are observed C_p and red continuous line is the fit of electron and lattice contributions by Debye and Einstein models. The inset: C_p / T vs. T² plots without magnetic field below T² = 200 K² with a linear fit. (b) C_p / T vs. T curves in various fixed applied fields from 0 kOe to 90 kOe. (c) Magnetic specific heat capacity C_mag / T (blue circles) and entropy S_mag (solid red line) as functions of temperature.
