Description

type:論文(Article)

The purpose of the present study is to answer the question:Does the electric resistivity, ρ, approach zero as theapplied electric current approaches zero,in the glassy state of the quantized fluxoids in a type 2 superconductor? Thebest method for answering the above question by experimental studies may be to measure the relaxation process ofthe induced electric field, ����, during ultra-long time in the concerning material. This kind of measurements are,however,very hard to perform,and hence,we tried to answer the above question by a theoretical approach. In thispaper, we propose the starting basic equations to investigate the present problem by a theoretical analysis or bynumerical calculations, because we have at present no established reliable theoretical formulation for describing theultra-long time relaxation process in the glassy state.
