Temperature-Dependent Infrared Reflectivity Studies of Multiferroic TbMnO_{3}: Evidence for Spin-Phonon Coupling

Pradeep Kumar, Surajit Saha, C. R. Serrao +2

We have measured near normal incidence far infrared (FIR) reflectivity spectra of a single crystal of TbMnO3 from 10K to 300K in the spectral range of 50 cm${}^{-1}$ to 700 cm${}^{-1}$…
