摘要
High-quality single-phase thin platelets of BSCCO-2223 have been produced by a novel method on thermal-gradient-enhanced KCl flux which allows the growth of the 2223-phase in an extremely short time interval compared to those reported in the literature. In-plane electrical resistivity measurements in zero applied magnetic field have been performed. Experimental data have been analysed and interpreted within the Aslamazov-Larkin theory of amplitude fluctuations and the Ginzburg-Landau Coulomb gas model of phase fluctuations. These theories seem to fit in a very reliable way the experimental R(T) curves.
