Abstract

In order to improve the magnetocaloric effects (MCEs), the partial substitution of Ce for La in the La(Fe_0.86Si_0.14) ₁₃ has been examined. The MCEs in the La_0.7Ce _0.3(F_0.86Si_0.14)₁₃ are much larger than those in the La(Fe_0.86Si_0.14)₁₃. The hysteresis loss due to the itinerant-electron metamagnetic transition of the La_0.7Ce_0.3(Fe_0.86Si_0.14) ₁₃ is smaller than that of La(Fe_0.88Si_0.12) ₁₃, though their MCEs are almost the same. Similar results are obtained in the case of z < 0.3. Accordingly, La_1-zCe _z(Fe_0.86Si_0.14)₁₃ compounds are useful for high-performance magnetic refrigerants.
