Cube-textured Si-Fe would be useful for applications in which magnetic flux is rotated, because it has two magnetic easy axes that are perpendicular to each other in the steel plane. We measured magnetostriction in the magnetization process for this material when the magnetic easy axis deviated from the exciting direction. Large contraction was observed in larger field than the changing point of inclination of the B-H loop. In addition, when we observed the magnetic domain structure, using Lorentz micrography, a supplementary domain appeared at edge of the sample at the point. We investigated the occurrence of this supplementary domain in detail.
