http://aflowlib.org/prototype-encyclopedia/monoclinic_lattice.html WebMoriya (DM) interaction with a DM vector perpendicular to the layer produces an easy-plane spin anisotropic Hamiltonian for honeycomb lattice. DM interaction breaks SU(2) symmetry of the model and reduces it to U(1) symmetry around the D vector. This DM interaction is believed to orient the spins in the 2D layer.

"WebThe next step is to normalize these vectors. If the molecule is linear (or is a single atoms), any vectors which do not correspond to translational or rotational normal modes are removed. The scalar product is taken of each vector with itself. If it is zero (or very close to it), then that vector is not an actual normal mode and it is eliminated. " - Lattice translational vector
