Abstract

PURPOSE:To acheive the improvement in magnetic characteristics in a frequency band of several 10Hz higher than commercial frequencies, particularly the reduction of iron loss, by making shape defects in the surface and inside of an amorphous magnetic alloy thin strip. CONSTITUTION:At the time of making an amorphous ribbon by discharging molten amorphous magnetic alloy 2 onto a roll 3 from a nozzle 1, horizontal scores 5 are beforehand made on the outside circumferential surface of the roll 3 in contact with the molten metal 2. These horizontal scores 5 are transferred to a ribbon 4, and this turns out that the ribbon 4 has horizontal scores. These horizontal scores need be made in a direction other than the direction substantially rectangular to the energizing direction of the time when the ribbon is energized.
