Fig. 6: Barocaloric properties under pressure.

For MnCo(Ge0.98In0.02) (left panels) and Mn(Co0.98In0.02)Ge (right panels): a, e Heat flow recorded during cooling and heating after baseline subtraction under selected pressures. Insets show the relationship between the transition temperature and pressure during heating (red symbols) and cooling (blue symbols). b, f Entropy‒temperature (S‒T) curves without considering the specific heat. The insets show the S‒T curves, including the specific heat. c, g Barocaloric entropy change ΔSP vs. temperature. d, h Reversible isothermal entropy change ΔSrev vs. temperature.
