Abstract EN
We report on the analyses of fluctuation induced excess conductivity in the ρ-T behavior in the in situ prepared MgB2 tapes.
The scaling functions for critical fluctuations are employed to investigate the excess conductivity of these tapes around transition.
Two scaling models for excess conductivity in the absence of magnetic field, namely, first, Aslamazov and Larkin model, second, Lawrence and Doniach model, have been employed for the study.
Fitting the experimental ρ-T data with these models indicates the three-dimensional nature of conduction of the carriers as opposed to the 2D character exhibited by the HTSCs.
The estimated amplitude of coherence length from the fitted model is ~21 Å.
