Query: Computer Simulations on Barkhausen effects and Magnetizations in Fe
  Nano-Structure Systems   The magnetization processes in Fe nano-systems are investigated using 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 most
of basic magnetization phenomena. The Barkhausen effects are represented with
jumps and terraces of magnetization steps induced from external field changes
of {\Delta}H.
