Infrared-active phonon modes in monoclinic multiferroic MnWO4
T. Möller, P. Becker, L. Bohaty +2
We report on polarized infrared reflectivity measurements of multiferroic, monoclinic MnWO4 between 10K and 295K. The full dielectric tensor and the frequency dependence of the ori…

Collective orbital excitations in orbitally ordered YVO3 and HoVO3
E. Benckiser, R. Rückamp, T. Möller +6
We study orbital excitations in the optical absorption spectra of YVO3 and HoVO3. We focus on an orbital absorption band observed at 0.4 eV for polarization E parallel c. This feat…
