A Reptation Model for Magnetic Materials

摘要

Reptation, or accommodation, is manifested in ferromagnetic materials in a variety of operating regimes and hence must be incorporated in models used for comprehensive material characterization or model-based control design. Because the microscopic mechanisms which cause reptation are complex, we characterize the effect in a phenomenological macroscopic manner within the context of a homogenized energy framework for ferromagnetic hysteresis. Attributes of the model are illustrated through comparison with experimental data.
