The anisotropy of the high-field susceptibility and the domain structure in plastically deformed iron single crystals

Abstract

The high-field susceptibility in ferromagnets in general is influenced by thermally excited magnons, the magnetocrystalline energy, and internal elastic stresses of dislocations. The anisotropy of the susceptibility was measured for the case of deformed iron single crystals. An analysis of the experimental results and the investigation of the domain structure shows that primary dislocations, as well as secondary dislocations, contribute to the susceptibility. The dislocations are present as groups of 16 dislocations which are arranged in layers parallel to the primary glide plane. The present paper gives a brief review of results obtained recently in a thesis of G. Schroeder [1].
