Amorphous alloys for magneto-acoustic markers having reduced, low or zero cobalt content, and associated article surveillance system |
摘要 |
A ferromagnetic resonator for use in a marker in a magnetomechanical electronic article surveillance system is manufactured at reduced cost by being continuously annealed with a tensile stress applied along the ribbon axis and by providing an amorphous magnetic alloy containing iron, cobalt and nickel and in which the portion of cobalt is less than about 4 at %.
