Abstract

Structural, magnetic, and magnetocaloric properties of iron-deficient (Nd_1−xCe_x)YFe₁₇ alloys in the rhombohedral Th₂Zn₁₇–type crystal structure prepared by arc-melting and vacuum annealing have been investigated. Among the investigated alloys, (Nd_0.7Ce_0.3)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 (Nd_0.7Ce_0.3)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 (Nd_0.7Ce_0.3)YFe₁₇ carries significant potential for room-temperature magnetic refrigeration.
