摘要

This paper is devoted to the surface and cross-sectional microstructural and magneto-optical investigations of the bilayered (BL) CoFeCrSiB-based ribbon of dissimilar Co/Fe content in the layers and to the comparison with the CoSiB/FeSiB ribbon, both prepared by planar flow casting. It is shown that the interface properties are strongly influenced by chemical compositions of the layers and mainly by the magnetostriction coefficients. This results in different magnetic domain patterns in the layers and across the interlayer and their changes with applied magnetic field intensity. While in the BL sample of a similar layer composition, the magnetic domains concentrate inside the layers, at the sample with completely different layer composition, the domains cross the interlayer.
