Extension of Hall symbols of crystallographic space groups to magnetic space groups

J. González-Platas, N. A. Katcho and J. Rodríguez-Carvajal

The Hall symbols for describing unambiguously the generators of space groups have been extended to describe any setting of the 1651 types of magnetic space groups (Shubnikov groups). A computer program called MHall has been developed for parsing the Hall symbols, generating the full list of symmetry operators and identifying the transformation to the standard setting.

Keywords: symbols for magnetic space groups; generators of magnetic space groups.

The newly proposed international symbols (to be discussed in the Commission for Magnetic Structures of the IUCr) for the standard settings are also in the list.
