Title: Magnetization modeling of silicon steel using a simplified domain structure model
Abstract: A simplified domain structure model with shape anisotropy and cubic crystalline anisotropy is applied to the analysis of the mesoscopic magnetization of silicon steel sheets. Alternating magnetization is analytically described by the transition among several magnetization states, such as the single-domain, 180∘ domain-wall-motion, and magnetization-rotation types. The magnetic field vector is calculated from a given average magnetization vector under the rotational magnetization condition. The loci of the magnetic field vector qualitatively reconstruct the rotational magnetization properties of non-oriented and grain-oriented silicon steel sheets.
