摘要

A series of intermetallic Er_3-xGd_xCo (x = 0.5-3) compounds were synthesized and their magnetic properties and magnetocaloric effects were investigated. The Neél temperature (T_N) could be tuned from 28 to 129 K by partially replacement of Gd with Er. For a field change of 5 T, the Er_1.5Gd_1.5Co exhibited a minimum -ΔS_M of 9.8 J/kg K and maximum refrigerant capacity power (RCP) value of 629 J/kg which originated from an enlarged temperature span of magnetic entropy change in the compound. Results demonstrate that it is a feasible way to search for a large RCP material from the compounds with two magnetic transitions and controlled temperature region.
