Petit We used Raman and terahertz spectroscopies to investigate lattice and magnetic excitations and their cross coupling in the hexagonal YMnO3 multiferroic. Two phonon modes are strongly affected by the magnetic order. Magnon excitations have been identified thanks to comparison with neutron measurement... [Phys. Rev.
