Abstract

The magnetocaloric effects (MCEs) and hysteresis loss in the itinerant-electron metamagnetic (IEM) transition process of La(Fe_0.86Si_0.14)₁₃ have been investigated by the partial substitution of Pr for La. The La_0.3Pr_0.7(Fe_0.86Si_0.14)₁₃ exhibits large MCEs in the magnetic field change from 0 to 5 T, which are almost the same as those of the higher Fe concentration of La(Fe_0.88Si_0.12)₁₃. Additionally, hysteresis loss in the IEM transition process of the former is smaller than that of the latter. Consequently, the La_1-zPr_z(Fe_xSi_1-x)₁₃ compounds are useful to realize large MCEs with smaller hysteresis loss as compared with that of La(Fe_xSi_1-x)₁₃.
