Description:
Author(s): M. Matsuda, R. S. Fishman, T. Hong, C. H. Lee, T. Ushiyama, Y. Yanagisawa, Y. Tomioka, and T. Ito We have determined the full magnetic dispersion relations of multiferroic BiFeO 3 . In particular, two excitation gaps originating from magnetic anisotropies have been clearly observed. The direct observation of the gaps enables us to accurately determine the Dzyaloshinskii-Moriya (DM) interaction and... [Phys. Rev. Lett. 109, 067205] Published Wed Aug 08, 2012
