  • Abstract
    The Lyapunov exponent is calculated and shown to be a positive value; this is a strict index to determine chaos. Controlling chaos of domain wall motion is demonstrated by using the OGY method. The domain wall is made to stand still at a saddle point or oscillate sinusoidally out of chaotic motion
