Abstract
A magnetomechanical resonance element or marker strip with facilitated performance based on an amorphous magnetostrictive alloy ribbon having a line-like surface pattern is utilized in an electronic article surveillance marker or sensor element. A direction of magnetic anisotropy at angle between 80 and 90 degree away from ribbon's length direction and in ribbon's plane is introduced during ribbon fabrication, which increases the resonance performance with minimal loss in the magneto-mechanical circuit, and more particularly, in a marker or sensor element utilizing a plurality of resonating elements or marker strips. A marker or sensor element is fabricated utilizing the resonance element or elements and is utilized in an electronic article surveillance and identification systems.
