Original Paper


It was investigated that the influence of Ca substitution by Zn on the specific resistivity, thermal power, and excess conductivity of Bi2Sr2CaCu2OX, Bi2Sr2Ca0.8Zn0.2Cu2OX, and Bi2Sr2Ca0.4Zn0.6Cu2OX polycrystalline samples in the 70–300 K temperature interval. The fluctuation-induced conductivity is analyzed using the Aslamasov and Larkin and Lawrence and Doniach models. The microscopic parameters such as dimensional crossover temperature (Tcr), interlayer coupling strength (J), and zero temperature coherence length along c axis (ξ0) are estimated.
