A magnetic domain twin consists of two magnetic domains which meet along a planar transition region called a domain wall. The symmetry of a magnetic domain twin consists of those symmetry elements which 1) leave both domains invariant and also leave invariant the normal to the domain wall or 2) interexchange the domains and invert the normal. The magnetic domain symmetry is a magnetic layer group. It is shown how forthcoming tables of the non-magnetic sectional layer groups of non-magnetic crystals (International Tables for Crystallography, Volume E (Kopsky and Litvin)) can be used to determine possible magnetic domain twin symmetry.
