Summary:
Energy localized vibrations known as intrinsic localized modes or discrete breathers were observed in a magnetically coupled cantilever array. It has been experimentally confirmed that the observed ILMs are stable against small perturbation. In this paper, it is shown that such stable ILMs can be destabilized by periodically varying on-site potentials. The destabilized ILM becomes a traveling ILM under the fixed boundary condition.
