| 中文摘要 | The magnetocaloric effects (MCEs) of LaFe13-xSix compounds doped by magnetic rare earths (R=Ce, Pr, and Nd) and transition metal (Co) are analyzed. It is found that varying the contents of R and Fe produces similar effects on the MCE, both of which cause a rapid decrease in Delta S with the increase in T-C. The Delta S-T-C relations thus obtained coincide with each other fairly well, which indicates the equivalence of substituting R for La and Fe for Si. In contrast, partially replacing Fe by Co leads to a slow decrease in Delta S with T-C. It is therefore a promising approach to maintain a large Delta S up to high temperatures. As a comparison with these element-doping compounds, the MCEs of hydrides are also discussed. Although interstitial hydrogen can also keep up a large Delta S to high temperatures, the corresponding hydrides are unfortunately unstable above 150 degrees C. Based on these analyses, the potential refrigerants made of LaFe13-xSix are proposed to have as low as possible Si content (or high R content) and proper Co content simultaneously.
