Cobalt-rich amorphous ribbon (Fe5.85Co72.15Mo2B15Si5) 13 mm in length and 5 mm in width were coated with different oxide layers in order to improve their GMI response. The coating process was performed using a chemical Successive Ionic Layer Adsorption and Reaction (SILAR) technique at room temperature. Oxide layer coated ribbons were imaged by an Atomic Force Microscopy (AFM). The variations in oxide layers and their roughness were studied to elucidate the cause of the improvements in GMI ratios in amorphous ribbons.
