摘要：

We have measured the surface hypersound velocity values VR of Bi2Sr2CaCu2O8 and Bi2Sr2CuO6 single crystals by Mandelstamm-Brillouin light scattering spectra. Measurements were performed at room temperature. In case of Bi2Sr2CaCu2O8 crystal considerable difference (20%) of (001) plane VR values along a and b crystallographic directions was manifested. However mentioned VR anisotropy in Bi2Sr2CuO6 crystals was not observed. © 1990.
