Abstract
Information concerning the dimensionality of the thermal flustuations of the new high temperature ceramic superconductors, can be derived from the excess conductivity (paraeonductivity) near the transition temperature according to Aslamasov-Larkin (AL) theory. Here the above dimensionality is derived from the excess resistivity and thermoelectric power measured in different samples of HTS materials such as YBaCuO and different Bi (PB) SrCaCuO compounds.
