In this research, we experimentally studied on control of intrinsic localized modes (ILMs) in a magneto-mechanical system. The magneto-mechanical system, which is a nonlinear coupled oscillator, consists of elastic beams corresponding to oscillators, permanent magnets, and electromagnets which create nonlinear restoring force. In this system, ILM was successfully excited and manipulated by locally adjusting the parameter. In addition, it was shown numerically that ILM loses its stability and begins to move by time-periodically modulated parameter of the system. It implies the feasibility of the control of ILM in nano-/micro-devices.
