Abstract

The magnetocaloric effect of Mn_3-xCo_xGaC has been investigated. Mn₃GaC shows a first-order antiferromagnetic to ferromagnetic transition at T_t = 160 K. Large magnetocaloric effects of ΔS_mag = 15 J/kgK, and ΔT_ad = 5.4 K were observed at the transition in an applied field of 2 T. The substitution of Co for Mn lowers T_t without significant loss of magnetocaloric effects. It was indicated that the system could cover a wide temperature range of 50-160 K by combining the compounds with various compositions from x = 0 to 0.05.
