Chubykalo-Fesenko, O and Chantrell, R W (2005) Modeling of long-time thermal magnetization decay in interacting granular magnetic materials. IEEE TRANSACTIONS ON MAGNETICS. pp. 3103-3105. ISSN 0018-9464Full text available as:
We present a general method to evaluate the long-time magnetization decay in granular magnetic systems. The method is based on Arrhenius-Neel kinetics with the evaluation of the energy barriers in a multidimensional space. To establish a possible reversal mode, we suggest the use of Metropolis Monte Carlo and for the mode statistical sampling-the kinetic Monte Carlo criteria. The examples considered include long-time magnetization decay in CoCrPt low-magnetization longitudinal recording media and in a collection of Co particles with different concentrations.
