Polar phonons and spin excitations coupling in multiferroic BiFeO3 crystals

P. Rovillain, M. Cazayous, Y. Gallais +4

Raman scattering measurements on BiFeO3 single crystals show an important coupling between the magnetic order and lattice vibrations. The temperature evolution of phonons shows tha…
