随着无取向硅铁电工板厚度的减小，反常系数有急剧增加的趋势。为了研究反常因子与薄层厚度的关系，利用克尔效应进行了磁畴观察。薄板材的颗粒呈现条纹域图案。在板材的横截面上，表面呈现条纹区的颗粒具有闭合磁区结构。研究发现，在薄板平面外加磁场会引起垂直于表面的磁化分量的变化，从而增加薄板的反常系数。
The anomaly factor tends to increase steeply when the thickness of non-oriented Si–Fe electrical steel sheets is decreased. To investigate the behavior of the anomaly factor in relation to the sheet thickness, magnetic domain observation was performed, using the Kerr effect. Grains of a thinned sheet exhibit a stripe domain pattern. The grains exhibiting the stripe domains on the surface had closure domain structure in a cross-section of the sheet. It was found that a field applied in the sheet plane induced changes of the magnetization component normal to the surface, which may increase the anomaly factor of thin sheets.
