Abstract

Results for the electrical resistance of the superconducting amorphous alloy Zr70lr30 (p=300 mW.cm and Tc=3.67K) are reported. The resistance increases by amount of 3.7 % on cooling from 300 K down to 10 K where it shows a hump, and then decreases rapidly approaching to Tc. Above 27 K any magnetoresistance (MR) is not detected, but, in 1.7K<T<27 K, the positive MR is observed and becomes saturated above Hs = 12-13 T. The saturated resistance in H=HS is greatly enhanced on cooling with a singular dependence,-log T. The para-conductivity near Tc due to the superconducting fluctuation is explained by the Aslamasov-Larkin term, indicating an absence of the Maki-Thompson mechanism.
