Název v původním jazyce

Surface magnetostriction of FeCoB amorphous ribbons analyzed using the magneto-optical Kerr microscopy

Popis výsledku v původním jazyce

Surface sensitive magneto-optical Kerr microscopy completed with the special self-made sample holder is used for studying magneto-elastic behaviour in the surface of the as-quenched amorphous Fe73Co12B15 alloy. The 10, 5, and 3 mm wide and approximately 34 μm thick ribbons were prepared by conventional planar flow casting process. The experimental setup allows a simultaneous application of external magnetic field in the directions parallel and perpendicular to the ribbon axis and of compression stress from one side of the sample resulted in tensile stress in opposite side. Distributions of tensile stresses in the measured surface were modelled by the Finite Element Method. Observed changes of the magnetic domains and hysteresis loop anisotropy field under applied stress are evaluated using the Becker-Kersten method. This results in determination of the local surface magnetostrictive coefficient from an area of about 200 μm in diameter. The obtained value ranges between 37 - 60 ppm and is well comparable with the bulk value presented in the literature.
