Abstract

The main and closure domain structures of cylindrical and prismatic 2.5% silicon‐iron single crystals with 〈110〉 axes are investigated using powder pattern technique and Kerr magnetooptic effect. The main domains are leaf‐shaped only in small effective fields. As closure domains we find on (110) faces the chess‐board structure at zero effective field and Q‐domains combined with the complicated zigzag pattern in the field range of magnetization rotation. The zigzag pattern is found to be independent of side face orientation in a wide range of orientation. Models of these closure domain structures are presented. Aspects of the calculation of the domain period and its field dependence are discussed.
