Fig. 6

a Heat flow measured at a temperature rate of 1 K/min under selected pressures; the inset shows the transition temperature Tt vs. temperature. b Entropy-temperature (S-T) curves without specific heat; the inset shows the S-T curves including specific heat. c Barocaloric entropy change ΔSp and d adiabatic temperature change ΔTp measured under a pressure of P ≤ 0.1 GPa. e ΔSp and f ΔTp obtained by linearly extrapolating the S curves to P = 0.4 GPa, and accordingly the obtained reversible g ΔSrev and h ΔTrev. The atmospheric pressure and P were taken as the initial values for the compression and decompression processes during the calculations.
