 Zusammenfassung: The Mn3WO6 oxide, prepared by a solid-state reaction at ambient pressure, is found to crystallize at room temperature in the centrosymmetric R3 trigonal structure of Mg3TeO6. By X-ray absorption spectroscopy (XAS) at the Mn-L-2,L-3 edges, a divalent oxidation state for manganese is established, consistent with W6+ and O2-, which fits with the value extracted from analyzing the paramagnetic regime. Interestingly, anomalies in dielectric and pyroelectric measurements can be observed concomitant with the antiferromagnetic transition at T-N approximate to 25 K. The corresponding electrical polarization, P = +/- 15 mu C m(-2) below TN, can be inverted by opposite poling, which confirms that Mn3WO6 is a spin-induced multiferroic (MF) material.
