Abstract

This paper reports an algorithm for the speed-up of micromagnetic simulation. We introduce interpolation vectors between discretized magnetization vectors in adjacent elements to accurately and rapidly simulate the magnetization configuration of a domain wall in a model with large mesh sizes. This method allows us to use numerical mesh elements double the size of the conventional one to calculate the coercivity of permanent magnets correctly.
