摘要

Mass data storage devices are the backbone of today'srnworld-wide connected society, and the development of magneticrnstorage devices has spurred technological advances inrna number of fields. Therefore, continuing research on magneticrnstorage devices and the development of new non-volatilernstorage concepts with ever higher storage capacity are inrngreat demand. Here we present an implementation of arnmicromagnetic model that describes the dynamics of magneticrnstructures on the nano- and micrometer scale intornMATLAB for a future inclusion into a multiphysics framework.rnWe explain the fundamentals of the micromagneticrnmodel and the architecture of the implemented code alongrnwith its performance. We found that our code is two- tornthree-times faster in a correct computation of one of thernstandard problems of micromagnetism than other software.
