摘要
用电弧炉熔炼法制备了Pr0．15Tb0．30Dy0.55Fe1．85Cx（x=0．0～0．1）合金。分别采用X射线衍射（XRD）、振动样品磁强计（VSM）和应变仪分析了合金的结构、居里温度和磁致伸缩。研究发现，所有样品均呈现单一MgCu2型Laves相结构；随C含量的增加，晶格常数增大、居里温度增高；C元素的引入，对合金的磁致伸缩和磁晶各向异性能产生了一定的影响。
Pr0.15Tb0.30Dy0.55Fe1.85Cx alloys （x=0.0-0.1） were fabricated by arc-melting method. The structure, Curie temperature and magnetostriction of compounds were investigated by means of X-ray diffraction, vibrating sample magnetometer and standard strain technique. All the samples show entirely MgCu2-type Laves phase structure. The lattice parameter and the Curie temperature increase with increasing C content. The magnetostrietion at room temperature and the crystal anisotropy energy are affected modestly by the addition of Carbon.
