FLUCTUATION GROWTH OF THE TRANSVERSE RESISTIVITY OF LAYERED SUPERCONDUCTORS AT THE EDGE OF TRANSITION

Superconducting fluctuations in strongly anisotropic planar supercondu ctors substantially affect the resistivity above the transition temper ature. In a wide temperature range above T-c, the main effect of these fluctuations is to create a virtual gap in the electronic spectrum, c ausing an increase of transverse resistivity. This effect becomes espe cially competitive due to the suppression of paraconductivity in c-axi s direction because of the hopping character of electron motion. The q ualitative aspects of the phenomenon are discussed in detail.
