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…

Interplay between magnetic and lattice excitations in BiFeO
M. Cazayous, A. Sacuto, D. Lebeugle +1
We have performed Raman scattering investigations on the high energy magnetic excitations in a BiFeO single crystal as a function of both temperature and laser excitation energ…
