| 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。 |

| Abstract: | 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 magnetostriction at room temperature and the crystal anisotropy energy are affected modestly by the addit... |
