摘要
The dynamic studies of the hyperfine interactions and the lattice vibrational behavior are performed by means of temperature-dependent Mossbauer spectroscopy and X-ray diffraction on Bi-2223 superconducting phases. The Mossbauer studies show the anomalous lattice effect taking place above, but relatively close to, the transition temperature. The anomalous decrease of the isomer shift reveal the delocalization effect of d-electrons.
