Summary:A method of manufacturing a marker for use in a magnetomechanical electronic article surveillance (EAS) system, the method comprising the steps of: - providing a magnetomechanical active element formed by planar strip of amorphous magnetostrictive alloy having a composition Fe a M b M o wherein a+b+c = 100, wherein a is in a range of 40-70 weight percent, b is in a range of 10-50 weight percent, and c is in a range of 10-50 weight percent, and where M is the balance of remaining elements; - subjecting the magnetomechanical active element to an annealing process for rearranging of the amorphous material in a short range, microscopic scale.
