Micromagnetic modeling simulations and applications

The advancement in micro and nano-scale technologies demands in depth understanding of magnetic behaviors. For example, as the ever increasing need for high capacity data storage continuously pushes the boundaries of magnetic recording technology to the physical limits, detailed analysis of the magnetic properties becomes necessary. It is expected that finite element micromagnetics can predict the magnetic behavior with high accuracy taking complex microstructure of magnetic materials into account. In practice, however, the tradeoff is speed and accuracy. This paper reviews the numerical methods used in micromagnetic simulations and presents practical examples in the field of nanotechnology and magnetic recording.
