Abstract

Nanocrystalline ribbons Fe-Cu-Nb-Si-B and Fe-Zr-B-Cu with high effective permeability μ_e, high saturation magnetic induction B_s, and low saturation magnetostriction λ_s can be fabricated by melt-spinning technique without additional annealing processes. We obtained magnetic properties of B_s=1.23 T, μ_e (at 1 kHz)=74300,λ_s=2×10^-6 for as-quenched nanocrystalline ribbon Fe₇₂Cu_2.5Nb₃Si_13.5B₉, and properties of B_s=1.55 T, μ_e (at 1 kHz)=27100,λ_s=-1×10^-6 for as-quenched nanocrystalline ribbon Fe₈₇Zr₇B₃Cu₃, respectively.
