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) The Nd2-xCexFe17 (x = 0.5, 0.8, 1.0) alloy was prepared by a vacuum high-frequency maglev furnace and the magnetocaloric effect of the sample was measured by direct measurement at a magnetic field of 1.3 T. The results show that the Curie temperature and adiabatic temperature ΔTad The maximum values ​​decrease with the increase of the Ce atomic fraction x.MegocalocaloriceffectinNd2-xCexFe17 (x = 0.5,0.8,1.0) WUZhong-wang1, XULai-zi2, HUANGJiao-hong2, LIUJin-rong2, JINPei-yu2, LIJie1, QIUJu- feng2 (1.
