| الوصف: | The paper reports on the temperature dependencies of the electrical resistivity and the a.c. magnetic susceptibility of the Tl0.8Bi0.3Sr1.8Ba0.2Ca2Cu3Ox bulk superconductor measured in the area of the transition from the metallic to the superconducting state. From the resistivity data, the onset temperature $T_{\mathrm {c,onset}} =$ 121.6 K, the critical temperature $T_{\mathrm {c50\% }} =$ 118.8 K, the zero resistance critical temperature obtained using $E =$ 10− 6 V/cm criterion $T_{\mathrm {c0}} =$ 117.9 K, and the width of superconducting transition ${\Delta } T =$ 1.6 K were derived. The thermal fluctuations were examined using the formulae for the conductance: ${\Delta } \sigma =K\varepsilon ^{-\lambda }$ , and for the magnetic susceptibility: χ = Ce−λ, where ${\Delta } \sigma = 1/R(T)-1/R_{R}(T)$ , $\varepsilon =~|$ (T − Tc)/Tc|, λ is the critical exponent, and $K $ and C are constants. The critical exponents in the transition region from the normal to the superconducting state were determined and analyzed. The three-dimensional fluctuations were found to occur in the vicinity of the zero-resistance critical temperature. |
