Magnetic structures (magCIF) version 0.9.8

_space_group_magn.OG_wavevector_kxkykz

Definition:

   
    The magnetic propagation vector (k) of the OG(k)-supercell
    description, which determines the time-reversal component of each
    translation vector (x) of the OG lattice (including the centering
    vectors if a centered setting is used) according to the expression
    cos(2*pi*k.x) = +/-1, where x is defined in the unitless coordinates
    of the direct-space OG lattice and k is defined in the unitless
    coordinates of the corresponding reciprocal-space lattice.  If 2*k.x
    has a non-integer value for any OG lattice (or centering) translation,
    the definition of k is incorrect.  The value of OG wave vector is
    essential to the OG(k) description of the magnetic space group
    symmetry; it cannot be omitted from such a description without
    ambiguity.
