| 中文摘要 | LaFe11.5Si1.5Hy interstitial compounds have been prepared by hydrogen absorption and subsequent desorption. The Curie temperatures are easily tunable for a wide temperature range from similar to195 to similar to340 K by hydrogen content. The maximal magnetic entropy changes, under a magnetic field change of 0-5 T, are as large as 16.8-20.5 J kg(-1) K-1, exceeding that of Gd (\DeltaS\ similar to 9.8 J kg(-1) K-1 at T-c = 293 K) by 70-110% in the vicinity of room temperature. The large magnetic entropy change of all hydrides may be attributed to the first-order itinerant-electron metamagnetic transition confirmed by the Arrott plots. Large \DeltaS\, convenient adjustment of T-c and small thermal and magnetic hystereses, make LaFe11.5Si1.5Hy interstitial hydrides promising candidates for magnetic refrigerants in the corresponding temperature range. |
