Abstract:This paper proposes the method to accurately predict the 180° basic domain width (Dw) in demagnetized states of the grooved Fe3%Si(110) single crystal with the tilt angle of [001] out of the sheet surface (β). The evaluation of Dw enables the estimation of the anomalous eddy current losses. In this paper, Dw is optimized to minimize the magnetic Gibbs free energy represented by vector potentials using the finite element method and the conjugate gradient method. The μ*-method is adopted to approximate the magne… Show more
