Abstract :
The authors have formulated a numerical approach for application to micromagnetics problems and have implemented the corresponding three-dimensional finite element code. The program has been applied to the study of hysteretic behavior and domain walls in a variety of samples. The authors discuss the numerical method and give results of its application to small, rectangular Permalloy particles
