Abstract

We prepared (Fe₅₀Co₅₀)_73.5Cu₁Nb₃Si_13.5B₉ amorphous ribbons and annealed that under different temperatures. Atom force microscope (AFM) was used to analyze its micro morphology. The AFM figures indicated the grain size of Co-doped Finemet alloy annealed at 540Â°C grew finer which attributes to the addition of Co. The complex permeability was measured by soft magnetic properties measuring system. The optimal soft magnetic properties can be obtained when (Fe₅₀Co₅₀)_73.5Cu₁Nb₃Si_13.5B₉ were annealed at a temperature range of 480~520Â°C.
