Abstract

The influences of Fe substitutions on magnetic properties, phase transformations and magnetocaloric effects of Mn₃Cu_1-xFe_xN have been investigated. The magnetic phase transition temperature (T_c) increases but the first-order phase transition temperature decreases with increasing the Fe content. Fe doping separates the first-order phase transition into first-order and second-order phase transitions in Mn₃Cu_1-xFe_xN. The second-order (paramagnetic-ferromagnetic) transition coexists with first-order (ferromagnetic-ferrimagnetic) transition in Mn₃Cu_0.95Fe_0.05N. Introduction of the second-order magnetic transition broadens the phase transition span, which greatly enhances the relative cooling power of Mn₃CuN. The results indicate that resolving complex magnetic phase transition may improve the cooling capacity of antiperovskite compounds.
