“…Apabila suhu diturunkan menghampiri T c bilangan pasangan Cooper bertambah dengan lebih cepat. Hasilnya rintangan sampel berkurangan disebabkan fluktuasi kekonduksian yang berlebihan (Aswal et al 2002). Fluktuasi dalam kekonduksian membolehkan dimensi kesuperkonduksian dan panjang koheren berhampiran suhu genting diukur (Islam & Paramanik 1997).…”

“…By decreasing the temperature from room temperature toward the critical temperature T c , the fluctuating Cooper pairs begin to be created spontaneously at a temperature around T f ≈ 2T c . 2 As the temperature approaches T c , the number of Cooper pairs increases while the normal electron density decreases. Therefore, the resistivity decreases and the thermal fluctuations induce excess conductivity ∆σ.…”

Polycrystalline samples of Nd 1-x Ca x Ba 2-x La x Cu 3 O 7-δ (with 0.0 ≤ x ≤ 0.15) were prepared by the standard solid state method. The co-doping effect was studied on the resistivity as a function of temperature and doping concentration x. The fluctuation conductivity was analyzed using the Aslamazov and Larkin model (AL). For all samples, three fluctuation regions; i.e. one-dimensional (1D), two-dimensional (2D), and three-dimensional (3D), were clearly observed with decreasing temperature. A critical region was also observed for high doping concentration (x ≥ 0.1). Superconductivity parameters such as the effective coherence length ξ p , the coherence length along the c-axis ξ c and ab plane ξ ab , the effective interlayer separation d, anisotropy parameter γ a , and the upper critical magnetic field B c2 along the c-axis and ab plane were obtained. It was also found that CuO x chains contribute to conducting.
