摘要

Abstract

Stress annealing is utilized for enhancing the magnetic softness of Fe

83–

(

= 0–16) amorphous alloys with saturation polarization up to 1.75 T. All of the stress-annealed alloys exhibit improved soft-magnetic properties

including low coercivity of 1.8–2.2 A/m

low core loss of 0.09–0.11 W/kg at 1.0 T and 50 Hz

and high permeability of 27

000–33

200 at 5 A/m and 1 kHz. Stress annealing induces longitudinal magnetic anisotropy and facilitates the annihilation of free volume

leading to pinning-free domain wall motion

and thus the enhanced magnetic softness. The induced magnetic anisotropy relates to the constrained elastic elongation introduced by stress annealing.
