Structural, magnetic, and magnetocaloric properties of iron-deficient (Nd1−xCex)YFe17 alloys in the rhombohedral Th2Zn17–type crystal structure prepared by arc-melting and vacuum annealing have been investigated. Among the investigated alloys, (Nd0.7Ce0.3)YFe17 shows the highest values of magnetic entropy change and relative cooling power, namely 5.45 J kg−1 K−1 and 504 J kg−1 for a magnetic field change of 5 T. The Curie temperature and saturation magnetization of the (Nd0.7Ce0.3)YFe17 alloy are 301 K and 162 emu/g, respectively. The absence of thermal and magnetic hysteresis with relatively high cooling capacity near room temperature suggests that Fe-deficient (Nd0.7Ce0.3)YFe17 carries significant potential for room-temperature magnetic refrigeration.
