The imbalance between the four fundamental magnetic interactions (the magneto-crystalline anisotropy, the exchange and magnetostatic interactions, and the Zeeman coupling) is responsible for a very large diversity of magneticbehaviors that researchers try to explore anduse for technical applications (data storage,sensors, memories, medical imaging …).
In this work, a finite element formalism (FE) is proposed to solve the micromagnetic equations. Two bi-dimensional test problems are treated to estimate the validity and the accuracy of this FE approach.
