Abstract :
The delayed feedback control of the magnetic domain-wall motion is investigated. In a specific range of the amplitude and the frequency of the external magnetic field, the magnetic domain-wall shows chaotic motion. In that case, the chaotic motion affects the thermal energy loss, the error or the noise in an electromagnetic system. It is shown that the chaotic motion of the magnetic domain-wall is controlled to the periodic motion by the delayed feedback control.
