A ferromagnetic resonator for use in a marker in a magnetomechanical electronic article surveillance system has improved magnetoresonant properties and/or reduced eddy current losses by virtue of being annealed so that the resonator has a fine domain structure with a domain width less than about 40 µm, or less than about 1.5 times the thickness of the resonator and an induced magnetic easy axis which is substantially perpendicular to the ribbon axis. |
