Tomography of basic magnetic domain patterns in ironlike bulk material

Abstract

The magnetic domains in bulk nontransparent magnetic specimens are not accessible by simply slicing the sample as the domains would immediately adapt to the new surface. Therefore tomographic imaging tools are required to disclose the complete domain structure. In this paper Libovicky tomography is applied to reveal the true three-dimensional structure of characteristic domain patterns in an ironlike material, which previously have been vaguely analyzed only by surface domain observation and by using arguments from domain theory to infer the inner domains.
