Computer Simulations on Barkhausen Effects and Magnetizations in Fe Nano-Structure Systems

抄録

The magnetization processes in regular lattice Fe nano-systems are investigated by means of the numerical simulations based on classical magnetic dipole moment interactions. The domain energies are calculated from moment-moment interactions over whole systems using large scale computing resources. The results directly show basic magnetization phenomena. The Barkhausen effects are represented with magnetization steps in external field changes of ΔH, which are composed of jumps ΔM_B and terraces ΔH_B.
