Description

Thermal diffuse scattering due to a transverse phonon (eparallel[010]) propagating along the [100] direction was found in electron-diffraction patterns of Tl-Ba-Ca-Cu-O with T/sub c/ of 117 K. The scattering has an intensity maximum at the middle between two fundamental spots along the <100> directions and its intensity increases with decreasing temperature. That is, the Tl oxide with high T/sub c/ exhibits the soft-phonon behavior
