Abstract
The temperature widths of the resistive transition as well as the thermal fluctuations of bulk (Bi0.6Pb0.4)(2)Sr2Ca2Cu3Ox superconductor with T-c,T-50% = 107.1 K were studied. The applied magnetic field widens the resistive transition according to the following formula: Iota T = CHm + Delta T-0. The value of exponent m = 0.44 suggests that there is strong pining of vortices, especially at lower temperatures. The critical exponents A of the conductivity were calculated using the following equation: Delta sigma = K epsilon(-lambda) , with the lambda(1) = 1.75 close to the zero critical temperature and lambda(2) = 3.77 at higher temperatures. These values were discussed within the available theoretical models.
