Name:
_space_group_symop_magn_operation.xyz

Definition:

   
     A parsable string giving one of the symmetry operations of the
     magnetic space group in algebraic form.  The analogy between
     parsable labels for magnetic and non-magnetic symmetry operations
     is perfect except for the fact that a magnetic symop label ends
     with an additional piece of information ("-1" or "+1") indicating
     that the operation is or is not time-reversed, respectively.
     This tag is intended for use with the BNS-supercell description
     of a magnetic structure.

-y,x,z+1/2,-1 a time-reversed 4_2 screw along (00z).
-y,x,z+1/2,+1 a non-time-reversed 4_2 screw along (00z).
