| 中文摘要 | The large magnetic entropy change and changes in the magnetic properties of the antiferromagnetic compound LaFe11.5Al1.5 caused by carbonization have been investigated. Both the parent compound LaFe11.5Al1.5 and its carbides crystallize in the cubic NaZn13-type structure. Carbonization brings about an obvious increase in the lattice parameter. The magnetic ground state is changed from an antiferromagnetic to a ferromagnetic one by carbonization. A considerable increase of Curie temperature, varying from 191 to 262 K with carbon concentration increasing from 0.1 to 0.5, is observed due to the decrease in the overlap of the Fe 3d wavefunctions caused by the volume expansion. Meanwhile, only a slight increase of the saturation magnetization is found as compared with the variation in Curie temperature. All the LaFe11.5Al1.5 carbides exhibit a considerable magnetic entropy change, comparable with that in Gd around the Curie temperature. Thus, one can get a large magnetic entropy change over a wide temperature range by controlling the carbon concentration. This large magnetic entropy change can be attributed to the high magnetization and a sharp drop in magnetization with increasing temperature near the Curie temperature. |
