    Study of crystal-field excitations and Raman active phonons in o-DyMnO3.

  • Original language description

    In DyMnO3 orthorhombic single crystals,the weak Raman active phonon softening below T=100 K is correlated with the study of infrared active Dy3+ CF excitations as a function of temperature and under applied magnetic field.We detect five H13/2 CF transitions that we predict with appropriate CF Hamiltonian and we confirm that the magnetic easy axis lies in the ab plane.While the CF energy level shifts below T=100 K reflect different displacements of the oxygen ions that contribute to the phonon softening,lifting of the ground state Kramers doublet degeneracy(30 cm-1) is observed below TN=39 K due to the anisotropic Mn3+-Dy3+ interaction, which could be responsible for the stability of the bc-cycloid ferroelectric phase.
