摘要：

internal friction measurements have been performed on the same Bi(2212) sample at 85 and 8 kHz, using composite bar techniques. A sharp internal friction peak occurs at 167 K at both frequencies which indicates the peak is associated with a structural change in the material. Neutron powder diffraction measurements support this proposal. (C) 1997 Elsevier Science B.V.
