A micromagnetic approach, based on the Monte Carlo algorithm, to the thermally activated magnetization reversal processes

The applicability of the Monte Carlo algorithm to the solution of different micromagnetic problems is discussed in terms of the results obtained from the simulation of thermally activated reversal processes. Our simulational results, supported by experimental data obtained in amorphous thin films an...

Description
Summary:The applicability of the Monte Carlo algorithm to the solution of different micromagnetic problems is discussed in terms of the results obtained from the simulation of thermally activated reversal processes. Our simulational results, supported by experimental data obtained in amorphous thin films and polycrystalline multilayers evidence the occurrence of non-Arrhenius relaxational behaviour characterized by a very slow variation of the macroscopic state of the system for times immediately after the application of the measuring field.
