Chaos of magnetic domain wall motion: Lyapunov exponent and controlling

Chaos of magnetic domain wall motion: Lyapunov exponent and controlling

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.

Zusammenfassung: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.
