Název v původním jazyce
Surface Magnetostriction of FeCoB Amorphous Ribbons Analyzed Using Magneto-Optical Kerr Microscopy
Popis výsledku v původním jazyce
Surface sensitive magneto-optical Kerr microscopy completed with the special self-madensample holder is used for studying the magneto-elastic behaviour in the surface of the as-quenchednamorphous Fe73Co12B15 alloy. The 10, 5, and 3 mm wide and approximately 34 m thick ribbonsnwere prepared by the conventional planar flow casting process. The experimental setup allows for ansimultaneous application of an external magnetic field in the directions parallel and perpendicularnto the ribbon axis and of compression stress from one side of the sample, resulting in tensile stressnin opposite side. The distributions of tensile stresses in the measured surface were modelled bynthe finite element method. The observed changes of the magnetic domains and hysteresis loopnanisotropy field under applied stress are evaluated using the Becker–Kersten method. This resultednin the determination of the local surface magnetostrictive coe cient from an area of about 200 m inndiameter. The obtained values ranged between 37–60 ppm and were well comparable with the bulknvalue presented in the literature.
