Abstract :
Magnetic hysteresis and Barkhausen noise for deformed micro magnetic clusters were simulated by pseudo-nonequilibrial Monte Carlo method. The magnetic hysteresis curve showed a little dip around zero magnetic fields. Barkhausen noise on the dip was stronger than ordinal Barkhausen noise around coercive force. The result suggests a new measurement to reveal deformation of micro magnetic clusters
