Morphology of the Heesch magnetic groups and associated magnetic aspects
Abstract
The structures of the 122 magnetic point groups (Heesch groups) and their relation to the structures of the 32 associated magnetic aspect groups, underlying point groups and invariant subgroups are studied and enumerated in a physically meaningful scheme. It is shown that in many instances the number of classes of a given group is simply related to the number of classes of an associated group, and these relations are given.
