Abstract

This paper demonstrates an object orientated GPU accelerated micromagnetic simulator designed to model the material characteristics of complex magnetic alloy systems. The GPU simulator is written in C++ and uses object orientated programming to create a class that stores the magnetic information required to solve the Landau-Lifshitz-Gilbert (LLG) equation for a distribution of magnetic objects. Each magnetic object can be assigned individual properties based on the alloy distribution of interest. The simulator is verified against standard problem 4 of the “Micromagnetic Modelling Activity Group” (μmag). Standard problem 4 is chosen as it provides a benchmark for the modelling tools ability to accurately predict the magnetisation dynamics of a 500 nm × 125 nm × 3 nm Permalloy thin film.
