Approximate Solution of the Magnetostatic Property of FeCoZr Thin Films with Stripe Domain

For a long time, much attention has been paid to the establishment mechanism of thin films with stripe domains, but little attention has been paid to its magnetization mechanism. In this article, a concise magnetization mechanism is proposed; the stripe domain is simplified into a special kind of equivalent laminated domain; through the calculation of the free energy, the magnetostatic property of the film is well described. The simplified model corresponds to the experiment data in principle, and it is useful to understand the magnetization process of the films with the stripe domain.
