AB - Spin-charge-lattice coupling mediated by multimagnon processes is demonstrated in multiferroic BiFe O3. Experimental evidence of two- and three-magnon excitations as well as multimagnon coupling at electronic energy scales and high temperatures are reported. Temperature dependent Raman experiments show up to five resonant enhancements of the two-magnon excitation below the Ńel temperature. These are shown to be collective interactions between on-site Fe d-d electronic resonance, phonons, and multimagnons. © 2009 American Institute of Physics.
