摘　　要：通过X射线衍射仪、差热扫描量热仪和振动样品磁强计研究Dy对Nd-Fe-Al非晶合金的热稳定性及磁性能的影响.结果表明,加入Dy可提高非晶合金的热稳定性,(Nd1-xDyx)60Fe30Al10(x=0,0.1,0.2)非晶合金的剩磁随Dy质量分数的增加呈单调下降趋势,矫顽力随Dy质量分数的增加而增加.Nd-Fe-Al非晶合金的矫顽力来源于稀土元素较大的磁晶各向异性场.The effect of Dy on thermal stability and magnetic properties of Nd-Fe-Al based bulk amorphous alloys was investigated by means of X-ray diffractometry （XRD）. Differential scanning calorimetry （ DSC ） and the vibrating sample magnetometer （VSM）. The results indicate that the thermal stability can be improved significantly by the addition of Dy. The remanence for （ Nd1-x Dyx ） 60 Fe30 Al10 （ x = 0,0. 1,0. 2 ） alloys decreases with increasing Dy mass fraction, but the coercive force increases. The coercive force for Nd-Fe-Al amorphous alloy comes of the large magnetocrystalline anisotropy field originated from its Ianthanon.
