Abstract
The present invention provides an amorphous alloy ribbon superior in magnetic characteristics and lamination factor by defining the slip property of the amorphous alloy ribbon surface in a specific range, that is, an amorphous alloy ribbon superior in magnetic characteristics and lamination factor produced by the single roll method, characterized in that the slip property of the ribbon surface satisfies the following equation:0.1≦≦1.0 where, F is the slip friction coefficient, P is the force pulling the intermediate part of the amorphous ribbon when applying weight from above to three amorphous ribbons stacked together, and M is the load applied from the top of the amorphous ribbon (5 kg).
