The increasing density in recording media has augmented the interests in magnetic structures with dimensions in the range of nanometers. The micromag-netic model, introduced by Landau and Lifshitz for the study of ferromagnetic materials, is the key to the study of nanoscale magnetic devices. It is important to the application of magnetic storage system, such as hard disk and magnetic random access memory MRAM.

In the thesis, we improve our Landau-Lifshitz-Gilbert solver based on Gauss-Seidel projection method into a more efficient, more accurate solver with more application capability. Parallel computing (MPI) and FFTW also had been employed in the simulation to accelerate the speed.

We also use our micromagnetic solver to study magnetic properties of nanowire arrays and multilayer structures.
