摘要：

Temperature dependent X-ray diffraction is carried out in order to study lattice vibrational behavior in Bi1.6Pb0.4Sr2Ca2Cu3-xFexOy (x=0 and 0.08 respectively). The study focuses attention on the (002) diffraction peak. The lattice parameters and the anomalous behavior of the intensity of the (002) peak show the existence of a lattice softening effect at approximately 130 and 200 K. The samples with different values of T-c show different vibrational behavior.
