Abstract

A phenomenological model (PM) is employed to simulate magnetocaloric effect (MCE) of amorphous Fe_22.5Co_22.5Ni_22.5Cr_22.5Zr₁₀ (FCNCZ) alloy. MCE parameters are concluded via simulation at 9 T. The full-width at half-maximum, relative cooling power and refrigerant capacity are 209 K, 188.5 J/kg, and 138.7 J/kg, respectively, revealing the potential of applying the magnetic refrigeration over a remarkable temperature range, including cryogenic temperatures, which is practical in cooling devices.
