Magnetic subgroups compatible with some given propagation vector(s) or a supercell


k-Subgroupsmag: Magnetic subgroups compatible with some given propagation vector(s) or a supercell.
The program k-Subgroupsmag provides the possible magnetic subgroups of the space group of a paramagnetic phase (gray group) which are possible for a magnetic ordering having a known propagation vector. The program provides the set of magnetic subgroups or a graph showing the subgroup-tree (grouped into conjugacy classes). In both cases, more information about the classes or subgroups can be obtained.

Other alternatives for the input of the program:

  • An alternative parent (non gray) magnetic group can be chosen.
  • Instead of the whole set of subgroups, the output can be limited to subgroups having a chosen common subgroup of lowest symmetry.
  • More than one wave-vector can be chosen.
  • The whole (or partial) stars of vectors can be introduced.
  • Instead of propagation wave-vectors, a supercell can be given. In this case, all subgroups with their lattice defined by the supercell are given, including the gray ones.

    • See the Help for details.
