Magneto-electric excitations in multiferroic TbMnO3 by Raman scattering
P. Rovillain, M. Cazayous, Y. Gallais +3
Low energy excitations in the multiferroic material TbMnO3 have been investigated by Raman spectroscopy. Our observations reveal the existence of two peaks at 30 cm-1 and 60 cm-1.…

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…
