摘要： A ferromagnetic resonator for use in a marker in a magnetomechanical electronic article surveillance system has improved properties and can be manufactured at higher annealing speeds and reduced raw material cost by virtue of being continuously annealed in the simultaneous presence of a magnetic field perpendicular to the ribbon axis and a tensile stress applied along the ribbon axis and by providing an amorphous magnetic alloy containing iron, cobalt and nickel in which the portion of iron is more than about 15 at% and less than about 30 at%.

摘要： A new manufacturing process is disclosed for tape wound core strips made of an amorphous ferromagnetic material. An amorphous ferromagnetic strip is first cast by quickly solidifying a molten mass consisting of a cobalt-based alloy with 1 to 10 % by atoms of iron and/or manganese as alloying metals. The amorphous ferromagnetic strip is then continuously subjected to a thermal treatment in a magnetic field transverse to the longitudinal direction of the strip. After the thermally treated amorphous ferromagnetic strip is cut into tape cores, the tape cores are wound up, preferably into annular tape wound cores. Inductive components exhibiting excellent magnetic properties can be produced with these tape wound cores, in particular inductive components whose annular tape wound cores have an average diameter d≤10 mm.
