Lattice dynamics and electron-phonon coupling in Sr2RuO4

Abstract

The lattice dynamics in Sr${}_2$RuO${}_4$ has been studied by inelastic neutron scattering combined with shell-model calculations. The in-plane bond-stretching modes in Sr${}_2$RuO${}_4$ exhibit a normal dispersion in contrast to all electronically doped perovskites studied so far. Evidence for strong electron phonon coupling is found for c-polarized phonons suggesting a close connection with the anomalous c-axis charge transport in Sr${}_2$RuO${}_4$.
