Abstract  

La1−xCex(Fe0.92Co0.08)11.4Si1.6 (x=0, 0.1, 0.3, 0.5) alloys were prepared by arc meltspinning. The structure and magnetic entropy change of annealed La1−xCex(Fe0.92Co0.08)11.4Si1.6 alloys (1000℃ for 3 h) were investigated using by X-ray diffraction (XRD) and magnetic properties. The results show that partial substitution of Ce for La in La1−xCex(Fe0.92Co0.08)11.4Si1.6 (x=0, 0.1, 0.3, 0.5) alloys, the cubic NaZn13-type structure phase is more easily formed, α–Fe phase is significantly reduced, Curie temperature is reduced to some extent, and the magnetic entropy change increases greatly. However the impurity phases appear when Ce substitution is up to 0.5, the magnetic entropy change decreases. The maximum isothermal magnetic entropy change of La1−xCex(Fe0.92Co0.08)11.4Si1.6 alloy with x=0.3 near room temperature is superior to that of Gd, suggesting that La1−xCex(Fe0.92Co0.08)11.4Si1.6 alloy with x=0.3 is promising to be low-cost, high efficiency magnetic refrigeration materials at room temperature.
