WebNeumann's principle, or principle of symmetry, states that, if a crystal is invariant with respect to certain symmetry operations, any of its physical properties must also be … In solid state physics, the magnetic space groups, or Shubnikov groups, are the symmetry groups which classify the symmetries of a crystal both in space, and in a two-valued property such as electron spin. To represent such a property, each lattice point is colored black or white, and in addition to the usual three-dimensional symmetry operations, there is a so-called "antisymmetry" operation which turns all black lattice points white and all white lattice points black. Thus, the m…

WebOverall symmetry is restored because symmetry-equivalent modes freeze in different domains.
