- 論文の詳細を見る
The orientation of 90° wall in iron has been studied theoretically by taking the effect of magnetostriction into account. The 90° domain is strained in order to keep the lattice coherency at the wall. The strain in the domain is calculated according to the continuum theory of dislocations. The stable wall orientation determined by the sum of the wall, elastic strain and magnetoelastic energies depends on the domain size: the angle between the wall and the plane containing the magnetization vectors increases from 62° to 90° with the domain size. This result is compared with the wall orientation determined experimentally from X-ray topographic images of 90° walls in iron whiskers. Agreement between the theory and experiment is satisfactory.
