High Performance Calculation of Magnetic Properties and Simulation of Nonequilibrium Phenomena in nanofilms

05/2012;
Source: arXiv

ABSTRACT Images of surface topography of ultrathin magnetic films have been used for
Monte Carlo simulations in the framework of the ferromagnetic Ising model to
study the hysteresis and thermal properties of nanomaterials. For high
performance calculations was used super-scalable parallel algorithm for the
finding of the equilibrium configuration. The changing of a distribution of
spins on the surface during the reversal of the magnetization and the dynamics
of nanodomain structure of thin magnetic films under the influence of changing
external magnetic field was investigated.
