Application of synchrotron topography to the study of magnetic domain movements in (100) Fe–3wt% Si produced by a mechanical stress

Tensile and compressive stresses up to about 10 MPa were applied along [010] direction of grain‐orientated (100) Fe‐3 wt% Si polycrystals. Stripe and chevron domains are observed in topographs obtained with white synchrotron radiation using about 10 s exposure times. When compressive stress is increased, [001] stripe domains or chevron closure domains are gradually replaced by [010] stripe domains. The width of the [010] stripe domains is decreased with increasing compression. The domains initially observed in the topographs at zero applied stress disappear when tensile stress of ⪆ 0.5 MPa is applied.
