On the Fluctuation Induced Excess Conductivity in Stainless Steel Sheathed MgB2 Tapes

Figure 2

(a) Variation of resistivity versus temperature for MgB2 tape sample, experimental curve, and the fit to AL-2D, AL-3D, and LD-layered expressions with  K are shown near the superconducting transition. The inset shows the same curves over the wide range of temperature—(15–250 K).
