| Description: | Speaker Andreas Lyberatos Affiliation Department of Materials Science and Technology, University of Crete Title Progress in multiscale modeling: A new cluster Monte Carlo method Location Department of Physics Bldg., Voutes, 3rd floor Seminar Room Time 16:00 Language English Abstract Multiscale modeling [1] aims at efficient and accurate simulation of thermomagnetic writing using micromagnetic models based on Landau-Lifshitz-Bloch equation with input parameters (for instance M(T), chi(T), Tc) determined separately from atomistic models. In the first part of this presentation I discuss some limitations in previous attempts at multiscale modeling and present a different methodology. A basic new requirement is the accurate knowledge of the size dependence of the equilibrium magnetic properties of the magnetic nanoparticles. For this reason, a new Monte Carlo cluster model for continuous spin models with long range exchange interactions is being developed to be applied on chemically ordered L1o-FePt.
