Impact of the spin-phonon interaction on the phonon properties of multiferroic hexagonal RMnO₃ thin films

Abstract:
The phonon properties of multiferroic hexagonal RMnO₃ thin films are studied based on a microscopic model including anharmonic spin-phonon interactions. We obtain an anomaly near the magnetic phase transition temperature T(N) which can be attributed to the magnetoelectric nature of RMnO₃ and a strong spin-phonon interaction. The size and surface effects on the phonon properties are discussed. It is demonstrated that the phonon energies can be larger or smaller for different substrates or doping ions, whereas their damping is always enhanced. The influence of an external magnetic field on the phonon properties is observed.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.

Qualitatively, any spin plus-half nucleus polarizes the spins of its electrons to the minus-half state. Consequently, the paired electron in the hydrogen–carbon bond must have a...
