ANNEALED AMORPHOUS ALLOYS FOR MAGNETO-ACOUSTIC MARKERS

摘要

A ferromagnetic resonator for use in a marker in a magnetomechanicalelectronic article surveillance system is manufactured at reduced cost bybeing continuously annealed with a tensile stress applied along the ribbonaxis and by providing an amorphous magnetic alloy containing iron, cobalt andnickel and in which the portion of cobalt is less than about 4 at%.
