Magnetic properties of Fe-(Nd, Sm)-B amorphous alloys

摘要

The magnetization behaviour of amorphous alloys Fe_(80-x)RE_xB_(20) (RE = Nd, Sm) with 0 ≤ x ≤ 16, prepared by melt-spinning technique. The effect of rare earth substitution on the magnetic properties (T_c, M_0, H_c…) of amorphous alloy has been investigated. Using Random Magnetic Anisotropy Model (RMA), we have analysed our results and obtained some fundamental parameters.
