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

Figure 1

(a) Resistivity versus temperature curve for the in situ prepared stainless steel sheathed MgB2 tape sample. In the inset, experimentally observed data for resistivity with temperature has been shown by the dotted (…) curve, and the fitted data ( ) in the normal state has been shown by the solid (—) curve. (b) Variation of resistivity (diamond symbol with continuous line) and the differential of the resistivity (triangle) with the temperature for the in situ prepared stainless steel sheathed MgB2 tape sample. (c) versus plot for determining , the linear extrapolated line hits the temperature where starts tending to zero.
