Relation between the coercive force and the internal stress in electrolytic iron films

Abstract

1. There is a relationship between the coercive force and internal stress for electrolytic iron films produced from sulfate electrolytes in the current density range 0.1–4 A/dm2; the coercive force increases as the internal stress decreases. 2. At low current densities the deposits presumably undergo two changes in grain size, transforming from fine-grain into coarse-grain deposits and back again. 3. At and above 0.5 A/dm2, Hc increases while σ increases, probably due to a further decrease in grain size.
