This research work focuses on studying the four micromagnetic fields, exchange field, anisotropy field, demagnetization field and applied field. Based on the related algorithms for programming given, a set of software for micromagnetics calculation is developed successfully in C++. Several attempts are also made to reduce the calculation complexity. Finally this program is verified with standard problem 3 from the mumag (or micromagnetics) society. It was also used to simulate a process with a specific initial state with spins pointing each other, and the result is discussed following. This program can also display the dynamic process of the simulation in MATLAB, which gives the information inside the material. More, this whole work is expected to be modified in order that it can easily take advantage of software platforms for parallel workstation, such as CACTUS for sharing the computer resource for further investigation.
