Abstract
A ferromagnetic fiber has been fabricated that has particular use in the field of electronic article surveillance (EAS). The ferromagnetic fiber is produced by using a spinning disk type of device that engages a bath of molten alloy having the desired compositions for the fiber. The use of ferromagnetic fibers has resulted in the ability to produce EAS markers of such a small length that they can be dispensed using a commercial labeler.
