We report on vortex transport in Bi2Sr2Ca 1-x Y x Cu2O8 crystals irradiated at different doses of heavy ions. We show evidence of a flux-creep resistivity typical of a variable-range vortex hopping mechanism as predicted by Nelson and Vinokur.

Resistivity Data

The resistivity of Li doped CuO polycrystalline samples is discussed following the variable-range hopping mechanism (VRH) form, exp ((T0/T)1/4), between 80 and 300 K. The T0 have been measured to be in the range of 107 − 108 K . In the CuO undoped system, the VRH mechanism does not fit appreciably the resistivity data in the range of temperature considered. However, when Li is introduced, this behaviour is followed, leading us to suggest that the Li doped CuO could be view as a disordered system. At higher temperatures, the thermal activation mechanism takes place.
