| 中文摘要 | The magnetic properties and magnetocaloric effects in NaZn13-type La1-x Pr-x Fe10.7Co0.8Si1.5 compounds have been investigated. Partially replacing La with Pr leads to a small reduction in the Curie temperature T-C due to the lattice contraction, but the values of T-C for La1-xPrxFe10.7Co0.8Si1.5 are close to room temperature. The maximum values of magnetic entropy change Delta S-m in La1-x PrxFe10.7Co0.8Si1.5 with x <= 0.5 are in the range 13.5-14.6 J kg(-1) K-1 for a field change of 0-5 T, and correspondingly the values of the refrigerant capacity (RC) are 373-353 J kg(-1). In particular, the values of Delta S-m and RC for a low field change from 0 to 2 T are also obtained to be as high as 7.0 - 8.1 J kg(-1) K-1 and 128 - 139 J kg(-1), respectively. No magnetic hysteresis is observed in the magnetization as a function of both the temperature and the magnetic field in the La1-xPrxFe10.7Co0.8Si1.5 compounds. The large reversible Delta S-m and the high reversible RC for a low field change indicate that La1-xPrxFe10.7Co0.8Si1.5 may be a promising candidate for magnetic refrigeration near room temperature. |
