SUPERCONDUCTING FLUCTUATION AND PARACONDUCTIV-ITY IN AMORPHOUS ZrCo ALLOYS
非晶ZrCo合金中的超导涨落和顺电导

The electrical resistance and low-field magnetoresistance have been measured on three dimensional ZrCo alloys. The data of magnetoresistance can be accounted for by the contributions from the quenching of superconducting fluctuation and weak localization. The former described by the Maki-Thompson correction is predominant at lower temperatures. The interaction in the particleparticle channel gives rise to a negative magnetoresistance.The paraconductivity phenomenon has been observed and found to be in good agreement with the theory, the (M-T) term plays an important role, the depression by the pair breaking effects due to thermal phonons may only be 10% of the term.
