Özet
The Y 3Ba 5Cu 8O 18 superconductors are synthesised using the solid state reaction method under different annealing conditions. Structure characterisation using X-ray diffraction shows that the lattice parameters are different from those of the standard YBCO system. The resistivity measurements are performed using the four-probe method in the temperature range from 77 to 300 K. The electrical resistivity indicates the transition temperature T c (O 2) = 100.2 K and T c (air) = 92.3 K. Thermal fluctuations were experimentally studied. The correlations of the critical exponents with the dimensionality of the fluctuation system for each Gaussian regime were performed using the Aslamazov-Larkin theory. Near T c, a critical regime with a critical exponent of λ CR = 0.35 is effectively described by the E-model. © Springer Science+Business Media, LLC 2012.
