The crystal structure, electromagnetic properties and magnetocaloric effect (MCE) of ternary iron-based ZnFe3N nitride have been investigated systematically. The density of states (DOS) calculation combined with theoretical model analysis suggests that ZnFe3N has a second-order ferromagnetic phase transition process existing in the cubic system. Its saturation magnetization (Ms) is about 108.3 emu/g at 5 K. The maximum values of magnetic entropy change (|ΔSM| = 2.2984 J/kg K) and relative cooling power (RCP = 247.0671 J/kg) are calculated from the measurements at a magnetic field change ΔH = 50 kOe, respectively.
