摘要： A resonator for use in a marker in a magnetomechanical electronic article surveillance system is composed of an amorphous magnetostrictive alloy containing iron, cobalt, nickel, silicon and boron in quantities for giving the resonator a quality Q which is between about 100 and 600. When the resonator is excited to resonate by a signal emitted by the transmitter in the surveillance system, it produces a signal at a mechanical resonant frequency fr which can be detected by the receiver of the detection system. Due to the resonator having a quality Q in the above range, a signal is produced having an amplitude at approximately 1ms after excitation which is no more than 15 dB below an amplitude of the signal immediately after excitation and having an amplitude at approximately 7 ms after excitation which is at least 15 dB below said amplitude at 1 ms after excitation.
