The Effect of Stress on the Domain Structure of Cube-textured Silicon Iron

Abstract

Observations were made of the domain structures on (001) surfaces of grains in 3% silicon-iron sheet when stresses were applied to the sheet. The changes produced by the application of a compressive stress along the [011] surface direction are described and discussed in terms of an extension of the theory proposed by Chikazumi and Suzuki in 1955. The effect of compressive stress was also investigated on surfaces which were inclined at angles of a few degrees to a (001) surface and an interpretation of the domain patterns is suggested.
