Abstract Scope |
Amorphous and nanocrystalline bilayer ribbons showing giant magnetoimpedance effect (GMI) can be used in design of magnetic sensors. Strategies for enhancement of their sensor performance include utilization of new alloys and/or novel geometries, better control of microstructure and improved processing methods. We show that besides the effects of field-annealing, the magnetic behavior in such bilayers is strongly influenced by interlayer stresses, which are induced in material due to different thermal expansion of two mechanically solid connected layers. The effects of magnetostatic interaction between layers can also play an important role in magnetization reversal process. Examples of our recent work on development of soft magnetic bilayer ribbons with enhanced magnetoimpedance characteristics will be presented and the application potential of such materials for use in magnetic sensors will be briefly discussed. This work was supported by the projects VEGA 2/0171/19, JRP SAS-TUBITAK MAGSAT and APVV-15-0621. |
