a Heat capacity as a function of temperature under various magnetic fields in the cooling protocol. b, Magnetization as a function of temperature under various hydrostatic pressures under a magnetic field of 0.05 T. The curves in the heating and cooling processes are indicated by solid and open circles, respectively. c Calculated adiabatic temperature as a function of pressure ΔTBCE by the transition distribution model. d Directly measured time-dependent adiabatic temperature curve under a pressure of 1 kbar at an initial temperature of 289.5 K, with the load maintained and the pressure released. e Adiabatic temperature change in response to the cyclic pressure change from 0-1-0 kbar. f Adiabatic temperature change as a function of temperature-induced by various magnetic fields using direct and indirect measurements. The indirectly measured ΔTMCE is from the data of heat capacity under magnetic fields (a).
