In-plane fluctuations of superconductivity have been investigated for Al-do
ped Bi-2212 single crystals with different resistivity anisotropy. The expe
rimental results of in-plane paraconductivity are in good agreement with th
e Lawrence and Doniach model. The interlayer coupling is found to decrease
with the resistivity anisotropy. (C) 2000 Elsevier Science B.V. All rights
