Isothermal entropy changes and . Solid curves 1 and 2 are the calculated magnetocaloric potential for magnetic field variation from at ambient pressure and for an applied pressure of , respectively. Open circles are experimental data (Ref. 19 ) of for a magnetic field variation from at ambient pressure. Dashed curves 3 and 4 represent the calculated barocaloric potential for pressure variation from and for applied magnetic fields of 2 and , respectively.

Adiabatic temperature changes and . Solid curves 1 and 2 represent the magnetocaloric potential for magnetic field variation from at ambient pressure and for an applied pressure of , respectively. Open circles are experimental data (Ref. 19 ) of for a magnetic field variation from at ambient pressure. Dashed curves 3 and 4 represent, respectively, the barocaloric potential for pressure variation from and for applied magnetic fields of 2 and .
