"Spin-phonon coupling and magnetic excitations in transition metal oxides"

Abstract

Magnetoelectric oxides are outstanding materials due to the strong interplay between polar and magnetic orderings. Underlying this effect, the spin-lattice coupling plays a key role, which can be studied through vibrational spectroscopy. In this talk, we will present an experimental study of the spin-phonon coupling and magnetic excitations in transition metal oxides, by means of Raman scattering spectroscopy at low temperatures and under magnetic field.
