The '''antisymmetric exchange''' arises when [[relativistic effect]]s, ''i.e'' the [[spin-orbit coupling]], are taken into account. The coupling between spins <math>\mathbf{S}_A</math> and <math>\mathbf{S}_B</math> on sites A and B respectively takes the form
<math>
H_{DM}=\mathbf{D}_{AB} \cdot ( \mathbf{S}_A \times \mathbf{S}_B )
</math>
where the coupling constant <math>\mathbf{D}_{AB} \propto (\mathbf{x} \times \mathbf{r}_{AB})</math> depends on the vector <math>\mathbf{r}_{AB}</math> connecting the site A to the site B, and on the displacement <math>\mathbf{x}</math> of the [[ligand]] ion from the AB line.

It is clear that the [[Dzyaloshinskii-Moriya Interaction]] is non-zero only for non-collinear spin configurations, and when the ligand atom doesn't belong to the AB line. The [[magnetoelectric effect]] arises when, upon the application of an electric field, the ligand ion moves inducing as a consequence [[spin canting]].
