Magnetic structures (magCIF) version 0.9.8
_space_group_symop_magn_operation.xyz
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. Analogous tags: symCIF:_space_group_symop.operation_xyz Ref: 'Magnetic Group Tables' by D.B. Litvin at http://www.iucr.org/publ/978-0-9553602-2-0. ISO-MAG tables of H.T. Stokes and B.J. Campbell at http://iso.byu.edu.Examples:
x+1/2,y+1/2,z,-1 | a time-reversed (1/2,1/2,0) translation, i.e. anti-centering vector |
-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). |
