“…The decreased density of free carriers in the conducting planes decreases the Fermi velocity V F = ( c / 2 ), coherence length c = ( K F /m2 ) and hence their order-parameter = (1.176K B T c ). In the previous experiments of Li-doping in Bi-2212 superconductors, it was found that the T c (R = 0) increases with the increase in Li content in the compound [32][33][34][35][36][37][38][39]. The reason of T c (R = 0) enhancement is suggested to be due the optimization of carriers in CuO 2 planes.…”

In the previous experiments of lithium doping in Bi-2212 superconductors it was found that the T c (0) increases with the increase of Li content in the compound [37][38][39][40][41][42][43][44][45]. In some of the papers the Li was substituted at Cu site in CuO 2 planes while some authors have substituted Li in the charge reservoir layer of Bi-2212 superconductor.…”

Samples with the nominal composition Bi,Sr,Ca, -,Li,Cu,O, (x = 0.2,0.4, and 0.6) and Bi,Sr,CaCu, -~ . Li,O, (x = 0.4,0.6, and 1.0) were prepared by the solid state reaction method. The role of Li at both Caand Cu sites in the Bi-2212 composition were studied. From the X-ray diffraction data it was found that the Li-doped at the Ca site increases the c-axis and that doped at the Cu site decreases the c-axis.From the D.C. four-probe resistivity data it was found that Li-doped at the Ca site reduces the T, and the Li-doped at the Cu site gives TJO) above the liquid nitrogen temperature. It was observed that the Li doping reduces the melting point of Bi-2212 composition. The presence of Lithium was confirmed by inductive the coupled plasma method.
