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.}, month = {Jan}, date = {2016-01-11}, organization = {2016 Joint MMM-Intermag Conference, San Diego (CA), 11 Jan 2016 - 15 Jan 2016}, cin = {PGI-5 / ER-C-1}, ddc = {530}, cid = {I:(DE-Juel1)PGI-5-20110106 / I:(DE-Juel1)ER-C-1-20170209}, pnm = {143 - Controlling Configuration-Based Phenomena (POF3-143)}, pid = {G:(DE-HGF)POF3-143}, typ = {PUB:(DE-HGF)16 / PUB:(DE-HGF)8}, UT = {WOS:000377962500267}, doi = {10.1063/1.4942954}, url = {https://juser.fz-juelich.de/record/827205}, }
