The effects of the interstitial C and H atoms on the phase formation, the hysteresis loss, and magnetocaloric effects of the NaZn13-type La(Fe, Si)13 compounds are investigated. It is found that the annealing time to obtain a 1:13 structure is significantly reduced from 40 days for LaFe11.7Si1.3 to a week for LaFe11.7Si1.3C0.2. The introduction of C and H atoms can adjust Curie temperature to around room temperature and leads to the decrease in magnetic entropy change (ΔSM) and magnetic hysteresis loss due to the weakening of itinerant-electron metamagnetic transition. Large −ΔSM of 19.0 J/kg K at room temperature without hysteresis loss for LaFe11.7Si1.3C0.2H1.7 is obtained for a field change of 5 T.
