Contribution
It provides direct experimental evidence of the localized mode in AOs2O6 compounds and characterizes its anharmonicity, advancing understanding of their lattice dynamics.
Findings
Localized mode identified in all compounds
Anharmonicity varies among A=K, Rb, Cs
Mode also observed in CsW2O6
Abstract
Inelastic neutron scattering and neutron powder diffraction experiments were carried out to investigate a localized mode, proposed from various bulk measurements, in the beta-pyrochlore AOs2O6 (A=K, Rb, Cs). The localized mode was identified in all the three compounds as well as another beta-pyrochlore CsW2O6. The anharmonicity of the mode is weak in RbOs2O6 and CsOs2O6 but substantial in KOs2O6.
