The extraordinary magnetocaloric effect ofFe₈₀P₁₃C₇bulk glassy rods has been studied. The magnetic entropy change (∆SM) and refrigerant capacity (RC) values under 1.5 T can reach 2.20 J kg-1 K-1 and 125 J kg-1, respectively, which are the largest values among present ternary Fe-based glassy alloys. It is found that the magnetocaloric effectvstemperature curve gradually changes into two peaks with increasing magnetic fields, leading to a much wider∆SM peak and thus a largerRC. This extraordinary magnetocaloric effect inFe₈₀P₁₃C₇may be attributed to the coexistence of magnetic transition and spin reorientation transition.
