摘要
用真空高频磁悬浮炉制备了Nd2-xCexFe17(x=0.5,0.8,1.0)合金,并用直接测量法测量了样品在1.3T磁场下的磁热效应.研究表明,合金的居里温度和绝热温度ΔTad最大值均随Ce原子分数x的增加而逐渐降低.MegnetocaloriceffectinNd2-xCexFe17(x=0.5,0.8,1.0)WUZhong-wang1,XULai-zi2,HUANGJiao-hong2,LIUJin-rong2,JINPei-yu2,LIJie1,QIUJu-feng2(1.MaterialScienceandEngineeringSchool,USTInnerMongolia,Baouou014010,China;2.BaotouResearchInstituteofRareEarth,Baotou014010,China)
Nd1.5 Ce0.5 Fe17, Nd12 Ce0. 8 Fe17 and NdCeFe17 compounds were prepared in a high-frequency floating furnace. The magnetocaloric effects in Nd1.5Ce0.5Fe17 ,Nd12Ce0.8Fe17 and NdCeFe17compounds were measured directly under the changes of magnetic field from 0 to 1.3 T. It is found that both the Curie temperature and the largest △ Tad in Nd2-xCex Fe17 （x = 0.5,0.8,1.0）decreased gradually with increasing x.
