Spin-Charge-Lattice Coupling through Multi-Magnon Excitations in Multiferroic BiFeO3 (2008)
Ramirez, M. O., Kumar, A., Denev, S. A., Chu, Y. H., Seidel, J., Martin, L., ...
Spin-charge-lattice coupling mediated by multi-magnon processes is demonstrated in multiferroic BiFeO3. Raman, linear and non linear optical spectroscopies show up to six resonant enhancements of the...
