Structure and properties of CoSiB/FeSiB alloys perspective for bilayer sensors

Abstract

The aim of this work is a detailed analysis of bilayered CoSiB/FeSiB ribbons and a comparison of its properties with structural and physical properties of the singlelayered FeSiB and CoSiB ribbons. All ribbons were prepared by rapid solidification of a melt using planar flow casting method. Microstructural and magnetic properties, from the viewpoint of ribbon surface, bulk and ínterface, were investigated by combination of various experimental methods. In the work it is shown that magnetic properties are determined predominantly by FeSiB layer. Moreover, the interconnection of two materials of different magnetostriction behavior and a formation of diffuse interlayer bring new features potentially available for sensing elements.
