Abstract:

It was investigated the influence of Ca substitution by Zn on the fluctuations of specific resistivity, thermal power and exsess conductivity of Bi2Sr2Ca0.6Zn0.4Cu2OX and Bi2Sr2Ca1Cu2OX in the 70-300К temperature interval. Experimental results explained taking into account strong anisotropy and multiband character of superconducting state in these compounds. The microscopic parameters such as dimensional crossover temperature (Tcr), interlayer coupling strength (J), and zero temperature coherence length along c axis (ξ0) are estimated.
