Abstract

Phonon dispersion of HgBa₂CuO_4+δ along the direction close to [100] was measured with using inelastic X-ray scattering. The longitudinal optical Cu-O bond stretching mode shows an anomalous softening at q∼0.3, similar to reports for other high-T_c cuprates, such as YBa₂Cu₃O_7-δ and La_2-x-Sr _xCuO₄. This feature indicates a common property in the high-T_c cuprates, independent of lattice distortion and transition temperature.
