摘要
The coercivity of soft magnetic films was intensively investigated some decades ago. Recently the coercive force in soft magnetic materials has been discussed again. In the present discussions the previous theoretical and experimental results are usually neglected. In this paper it is demonstrated that in polycrystalline uniaxial soft magnetic films the wall coercive force is expressed as H-W alpha S root D-4 root K-u/M(S), where S is the ripple parameter, D the mean diameter of the crystallites, and K-u the uniaxial anisotropy constant.
