<p>A resonator, having a width no larger than about 13 mm, 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 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 wherein 15 ≤ a ≤ 30, 6 ≤ b ≤ 18, 27 ≤ c ≤ 55, 0 ≤ x ≤ 10, 10 ≤ y ≤ 25, 0 ≤ z ≤ 5, 14 ≤ x+y+z ≤ 25, such that a+b+c+x+y+z = 100. The ferromagnetic ribbon is annealed in a magnetic flied 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. If multiple resonators are formed, the elements are placed in registration. The resulting narrow (6mm wide) resonator has properties comparable to the properties of wider resonators, such as the conventional 12.7 mm wide resonator.</p> |
