摘要

The effect of the B-addition on magnetic entropy change Δ S _M and hysteresis loss in La (Fe,Si) 13 is studied. The maximal values of Δ S_M for LaFe11.9 Si1.1, LaFe11.5 B0.4 Si1.1, LaFe11.5 Si1.5, and LaFe11.0 B0.5 Si1.5 are found to be 27.0, 26.1, 23.7, and 21.2 J/kg K at Curie temperature T_C for a field change in 0-5 T, respectively. The maximal hysteresis losses around T_C are 43 and 21 J/kg for LaFe11.9 Si1.1 and LaFe11.5 Si1.5, respectively, while almost no magnetic hysteresis is observed for the B-doped compounds. Our result reveals that a large Δ S_M and a small hysteresis loss can be simultaneously achieved in NaZn13 -type La (Fe,Si) 13 compounds by the addition of B.
