Abstract: (1402 Views)
Magnetic nanocrystalline bands are considered because of their special magnetic properties and good geometry. In this paper, the effect of folding on the magneto-optical Kerr response of Fe78Si9B13 nano crystal ribbons in longitudinal geometry has been investigated. In one sample, one fold and in the other three folds developed and their magneto-optical response were compared to the intact sample. Since the magneto-optical Kerr effect (MOKE) studies the surface magnetic properties of the material, in order to compare the results and analyze the bulk magnetic properties, the hysteresis loop of the samples has been measured and reported by vibrating sample magnetometry (VSM). The obtained results confirm the effect of folding on the longitudinal magneto-optical Kerr response (the surface properties) and the hysteresis loop of vibrating sample magnetometry (VSM) (the bulk properties). In the samples with more folding, the residual loop diagram obtained from the magneto-optical Kerr response has a wider width and the hysteresis loop obtained by vibrating sample magnetometry (VSM) has a lower slope which both of these results may be due to the increased magnification of the congestion in magnetic walls.
