Anti-ferromagnetic interaction in double perovskites probed by Raman Spectroscopy.

In this paper we show that Raman spectroscopy is a powerfull technique to detect antisite disorder into A2B'B"O6 magnetic double poerovskites whose ferromagnetic properties are driven by superexchange interactions. We could detect low antisite disorder levels by monitoring the coupling between the magnetic order and the phonons in low-level disordered La2CoMnO6 double perovskite.
