The effect of Cu addition on the soft magnetic properties of Fe–Zr–Si amorphous alloy was investigated by X-ray analysis, TEM observation, and B-H curve tracer. As a melt-spun amorphous ribbon sample was annealed above the crystallization onset temperature, very fine α-Fe particles smaller than ∼15 nm were precipitated and uniformly distributed in an amorphous matrix. Cu addition to Fe–Zr–Si amorphous alloy annealed above the crystallization onset temperature resulted in decreased coercivity and increased saturation magnetization and permeability.
