Abstract :
Angle dependence of magnetic hysteresis and Barkhausen noise for a micro magnetic cluster with one dislocation loop was simulated by pseudo-nonequilibrial Monte Carlo method. The magnetization curves showed angle dependence around zero magnetic fields. Simulated Barkhausen noise also showed difference between applied magnetic field directions. We propose usefulness of angle resolved analysis of magnetic dynamic process to evaluate magnetic clusters
