a) Specific heat of the Nb3Sn superconductor showing thermal fluctuations close to Tc
b) Isothermal magnetocaloric coefficient of the Nb3Sn supercondcutor showing a peak effect close to Hc2
c) Specific heat of the Nb3Sn superconductor at fixed temperature during a field sweep using an ac method. All curves have been taken using the same calorimeter with different AC and DC techniques.
| Specific heat with ramping the temperature up or down. |
| Magnetocaloric effect with ramping the field up to ±15 T. |
