Abstract

Magnetic flux in soft magnetic alloy Fe_73.5Cu₁Nb₃Si_13.5B₉ was investigated by electron holography coupled with a thickness mapping method. First the reconstructed phase image of a soft magnetic material with a simple wedge shape was simulated, and the contribution of both magnetic flux and inner potential to the reconstructed phase image was estimated. In the experiment, the magnetic flux was evaluated by removing the effect of inner potential with thickness mapping. The magnetic flux density of Fe_73.5Cu₁Nb₃Si_13.5B₉ obtained was 1.21 T which agreed well with that of a bulk specimen (1.28T).
