Lattice excitations in NdFeO3 through polarized optical spectroscopies

Popis výsledku v původním jazyce

The possibility of inducing new polar and/or magnetic transient states through the pumping of optical phonons towards the non‑linear regime has renewed the scientific interest in orthoferrites. In this work, we present a complete characterization of the optically‑active zone‑center phonons in NdFeO3 single crystals at room temperature by means of polarized Raman and infrared spectroscopies. The study is complemented with polarized infrared spectroscopy at 4 K and unpolarized Raman scattering at 10 K. The predicted polar phonons were successfully observed together with some of the crystal‑field excitations. First‑principles simulations further allow the eigenmode and symmetry assignments of the optical phonons. The calculated atomic motions of each mode are of significant interest, as they are common for all orthoferrites and to most of the large family of orthorhombic Pbnm perovskites.
