dc.description.abstractWe report electrical transport properties of Bi2Sr2Ca2Cu3O10+x(Bi-2223) superconducting thin filmsfabricated by pulsed-laser deposition on SrTiO3 substrate. The aim of the study was to investigate the influence of preparation conditions such as deposition temperature (T-S), annealing time (t(A)) and deposition rate (r). A critical temperature (T-c) as high as 110 K and critical current density (J(c)) of 6.2 x 10(6) A/cm(2) at 20K were obtained for T-S = 760 degrees C, t(A) = 4 h and r = 1.5 angstrom/s. We also investigated the effect of Li doping on Bi-2223 thin films. Li intercalation results in high resistive onset transition temperature and the resistivity shows broadening in magnetic field that increases with field. The large broadening of resistivity curve in magnetic field suggests that this phenomenon is directly related to the intrinsic superconducting properties of the copper oxide superconductors. The sudden drop in J(c) at relatively low magnetic field (H<0.5 tesla) is due to the effect of Josephson weak-links at the grain boundaries.en_US
