Abstract
Ce1-xDyxFe1.9(x = 0, 0.02, 0.05, 0.1) alloys were prepared successfully by means of arc-melting and the following homogenization. XRD patterns show all alloys are indexed as MgCu2-type C15 cubic Laves phase structure. With the Dy substitution of Ce, the Curie temperatures from ferro-to para-magnetism become gradually enlarged. The values of for a magnetic-field change from 0-5 T at 234, 246, 268, 303 K are 31.7, 26.4, 21.8, and 17.2 J kg-1K-1for x = 0, 0.02, 0.05, and 1, respectively.
