Fast codes for modeling the magnetization dynamics in magnetic nanostructures

摘要

Fast coupled micromagnetic-electromagnetic solvers are presented. The solvers allow modeling the non-linear magnetization dynamics in complex magnetic structures accounting for dynamic eddy current interactions. The solvers rely on a concurrently integrating in time of the Landau-Lifshitz-Gilbert equation and time-domain electromagnetic integral equation in the magneto-quasi-static approximation. The solvers are implemented on multi-core CPU and high-performance GPU computer systems.
