uperconducting wires have been prepared by Bi 1.6 Pb 0.4 Sr 2 Ca 2 Cu 3 O 10 (Bi-2223) coating of a great number of different metallic cores. The best electrical results (high T c0 and small ΔT c ) were obtained with silver and silver coated iron co

Using torque magnetometry in the Shubnikov state, we have studied the London penetration depth {lambda}{sub {ital ab}}({ital T}) of Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+{delta}} and (Pb{sub {ital x}}Bi{sub 1{minus}{ital x}}){sub 2}Sr{sub 2}CaCu{sub 2

We report on microwave emission experiments of Bi/sub 2/Sr/sub 2/CaCu/sub 2/O/sub 8+y/-single crystals at frequencies between 12 GHz and 95 GHz. Due to the intrinsic Josephson effect these samples form series connections of typically 2000 contacts. F

Pour qu'un fil supraconducteur gaine d'argent presente une capacite de transport de courant elevee ainsi qu'une bonne tenue sous champ, il faut que la phase Bi2223 soit exempte de phases residuelles, soit bien cristallisee en feuillets orientes dans

An experimental study of the magnetic irreversibility lines has been carried out on superconducting single crystals of Bi 2− x Pb x Sr 2 CaCuO 2 O 8 , with and without lead. The irreversibility field values B irr ( T ) are almost identical for x =

We have deposited, by an in-situ laser ablation technique, multilayers composed of thin films of the (2212) bismuth cuprate phase alternating with films of either of two insulating solid solutions Sr 14−x Ca x Cu 24 O 41 and Ca x Sr 2−x CuO 3 . T

The in-plane ( rho /sub ab/) and out-of-plane ( rho /sub c/)/sub c/ resistivities were measured above the critical temperature, T/sub c/, in several lead-substituted single crystals of Bi/sub 2/Sr/sub 2/CaCu/sub 2/O/sub 8+y/ and compared to the resul

We show that lead-substitution in single crystals of Bi2Sr2CaCu2O8+y induces a decrease of both the structural and resistivity anisotropies. In the first place we have found that lead substitution can reduce the resistivity anisotropy ρcρab by two

17O NMR spectra are obtained in a powdered sample of (Bi, Pb)2Sr2Ca2Cu3Oy, and resonance lines from oxygen sites in the two unequivalent CuO2 planes are clearly distinguished. The results presented here concerning the temperature dependence of the co
