Abstract

Intrinsic magnetic properties (saturation magnetization, anisotropy fields, and Curie temperatures) of Ce2Fe14B doped with Al, Ni, and Si are presented. Substitution for Fe by these elements leads to the formation of solid solutions that crystallize in the tetragonal Nd2Fe14B structure. Substituting Al, Ni, or Si for Fe leads to a decrease in both the saturation magnetization and the anisotropy field of Ce2Fe14B. Ni and Si increase the Curie temperature of Ce2Fe14B while Al reduces it. While, for the Ce2(Fe14−xTx)B containing Ni, a maximum Curie temperature of 210 °C was observed at 9 atom % Ni (x = 1.45), the highest value of 252 °C was found for the Ce2Fe14B containing 14 atom % Si (x = 2.26).
