| 中文摘要 | The LaFe11.5Si1.5H1.3 interstitial compound has been prepared. Its Curie temperature T-C (288K) has been adjusted to around room temperature, and the maximal magnetic entropy change (\DeltaS\ similar to17.0J(.)kg(-1.)K(-1) at T-C) is larger than that of Gd (\DeltaS\ similar to 9.8 J(.)kg(-1.)K(-1) at T-C=293 K) by similar to73.5% under a magnetic change from 0 to 5 T. The origin of the large magnetic entropy change is attributed to the first-order field-induced itinerant-electron metamagnetic transition. Moreover, the magnetic hysteresis of LaFe11.5Si1.5H1.3 under the increase and decrease of the field is very small, which is favourable to magnetic refrigeration application. The present study suggests that the LaFe11.5Si1.5H1.3 compound is a promising candidate as a room-temperature magnetic refrigerant. |
