Intrinsic Magnetic Properties of Ce2Fe14B Modified by Al, Ni, or Si.

Intrinsicmagnetic properties (saturationmagnetization, anisotropy fields, andCurie 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(Fe_14-xT_x)B containingNi, amaximumCurie temperature of 210 °Cwas 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).
