abstract = {Fe-Si-B-Nb-Cu alloys are attractive for high frequency
applications due to their low coercivity and high saturation
magnetization. Here, we study the effect of stress annealing
on magnetic microstructure in Fe73.5Si15.5B7Nb3Cu1 using
off-axis electron holography and the Fresnel mode of Lorentz
transmission electron microscopy. A stress of 50 MPa was
applied to selected samples during rapid annealing for 4 s,
resulting in uniaxial anisotropy perpendicular to the stress
direction. The examination of focused ion beam milled
lamellae prepared from each sample revealed a random
magnetic domain pattern in the sample that had been rapidly
annealed in the absence of stress, whereas a highly regular
domain pattern was observed in the stress-annealed sample.
We also measured a decrease in domain wall width from ∼ 94
nm in the sample annealed without stress to ∼ 80 nm in the
stress-annealed sample.},
