Cheong, and Je-Geun Park Using the inelastic neutron scattering technique, we measured the spin wave dispersion over the entire Brillouin zone of room temperature multiferroic BiFeO 3 single crystals with magnetic excitations extending to as high as 72.5 meV. The full spin waves can be explained by a simple Heisenberg Hamilt... [Phys. Rev. Lett. 108, 077202] Published Tue Feb 14, 2012
