Magnetic dynamic processes for micromagnetic clusters with local disorder of crystal structure were simulated by pseudo-non-equilibrial Monte Carlo method. The magnetic field dependence of magnetization showed a little dip at zero magnetic fields. The dip becomes larger as the number of dislocations increase. Simulated Barkhausen noise at the dip was stronger than ordinal-simulated Barkhausen noise around coercivity. The snapshot of spins shows a magnetic fluctuation around dislocations. The result suggests a possibility of a new measurement with high sensitivity, to detect the deformation of micromagnetic clusters.
