Parent category:
MAGNETIC

Definition:

   
     This category provides information about the space group and
     setting of  a non-magnetic parent structure which is related to
     the present magnetic  structure by a group-subgroup relationship.
     In general, the choice of a parent structure is not unique; it
     could be the lowest-symmetry non-magnetic structure obtained by
     simply setting all magnetic moments to zero, or a higher-symmetry
     approximation to this structure which idealizes some of the
     atomic coordinates.  The designation of a parent  structure is
     common but optional for a magnetic-structure description. This
     category could also be used to designate high-symmetry parent
     structures  of low-symmetry non-magnetic structures. As an
     alternative to this category, one can define a parent structure
     in a separate data block, and then relate the parent and child
     space-group settings by conveying an appropriate inter-data-block
     basis transformation in each data block.
