Electromagnons in multiferroic RMn2O5 compounds and their microscopic origin
A. B. Sushkov, M. Mostovoy, R. Valdes Aguilar +2
We summarize the existing experimental data on electromagnons in multiferroic RMn2O5 compounds, where R denotes a rare earth ion, Y or Bi, and discuss a realistic microscopic model…
Spin phonon coupling in frustrated magnet CdCrO
R. Valdés Aguilar, A. B. Sushkov, Y. J. Choi +2
The infrared phonon spectrum of the spinel CdCr2O4 is measured as a function temperature from 6 K to 300K. The triply degenerate Cr phonons soften in the paramagnetic phase as temp…
Colossal magnon-phonon coupling in multiferroic EuYMnO
R. Valdés Aguilar, A. B. Sushkov, C. L. Zhang +3
We report the spectra of magnetically induced electric dipole absorption in EuYMnO from temperature dependent far infrared spectroscopy (10-250 cm). Th…
IR Phonon signatures of multiferroicity in TbMnO
R. Valdés Aguilar, A. B. Sushkov, S. Park +2
The infrared (IR) active phonons in multiferroic TbMnO are studied as a function of temperature. Most of the symmetry allowed IR modes polarized along the \textit{a} and \t…
Temperature dependent optical studies of TiCoO
S. Guha, K. Ghosh, J. G. Keeth +5
We present the results of Raman and photoluminescence (PL) studies on epitaxial anatase phase TiCoO films for = 0-0.07, grown by pulsed laser deposition. The lo…
