The magnetocaloric effects (MCEs) in La1−zPrz(Fe0.88Si0.12)13 and their hydrides have been investigated. The values of the MCEs due to the itinerant-electron metamagnetic transition are enhanced significantly by a partial substitution of Pr for La. Furthermore, the Curie temperature TC of the La1−zPrz(Fe0.88Si0.12)13 is controlled by adjusting the absorption content of hydrogen in a similar manner as La(Fe0.88Si0.12)13. For the compounds having almost the same TC, the MCEs in the La1−zPrz(Fe0.88Si0.12)13Hy are larger than those in La(Fe0.88Si0.12)13Hy. To conclude, the La1−zPrz(Fe0.88Si0.12)13 and their hydrides are more useful for magnetic refrigerants working in a wide temperature range covering room temperature.
