<P>PROBLEM TO BE SOLVED: To provide a magneto-acoustic marker having reduced size without degrading its performance. <P>SOLUTION: A resonator for use in a marker containing a bias element which produces a bias magnetic field in a magnetomechanical electronic article surveillance system is produced from an annealed ferromagnetic ribbon having a basic composition FeaCobNicSixByMz (wherein a, b, c, x, y and z are in at%, wherein M is one or more glass formation promoting elements and/or one or more transition metals, and further, 46≤a≤53, 0≤b≤2, 30≤c≤35, 1≤x≤2, 15.5≤y≤16.5, 0≤z≤0.5 and a+b+c+x+y+z=100 are satisfied). The ferromagnetic ribbon is annealed in a magnetic field oriented perpendicularly to the ribbon axis and/or while applying a tensile stress to the ribbon along the ribbon axis. Single resonator or multiple resonator assemblies can be formed by cutting elements from the annealed ribbon. <P>COPYRIGHT: (C)2011,JPO&INPIT |
