Abstract

The Curie temperature TC of La1-zCe z(Fex-y,Mny,Si1-x)13 is decreased by adjusting the composition, and hence the itinerant-electron metamagnetic transition is observed at 5 K in La0.75Ce 0.25(Fe0.850Mn0.035Si0.110) 13 after zero-field cooling. As a result, the La1-zCe zFexMnySi1-x)13 compounds exhibit strong magnetocaloric effects in relatively low magnetic fields in a wide range of temperatures between about 19 and 180 K. Consequently, the La 1-zCez(Fex-yMny,Si 1-x)13 compounds are useful for the magnetic refrigerants working at low temperatures.
