Abstract
Lorentz electron microscopy was used to analyze the domain structure in few ferromagnets (pure Ni, Fe, Co) with ultrafine grained structure produced by high pressure torsion. The comparative analysis allows to conclude about the governing role of magnetic anisotropy constants For low anisotropic ferromagnets it has been established, that the domain structure does not depend strongly on grain size.
