- Abstract
We report experiments on conductivity fluctuations in the La1,82SR0,18CuO4 superconductor, by using results of resistivity measurements. The analysis was performed by using the temperature logarithmic derivative concept. Gaussian 3D and 2D, fluctuation regimes was identified near Tc. An intermediate exponent was determined, which was interpreted as a fractal fluctuation regime. Close to Tc a genuine critical regime was identified, which is good described by the 3D-XY model.
