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.}, year = {2009}, journal = {Applied Physics Letters}, volume = {94}, number = {16}, issn = {00036951}, doi = {10.1063/1.3118576}, note = {cited By 38}, language = {eng}, }
