چکیده

Ž . Ž . Superconductor films 25–125 mm thick were melt-grown under an elevated magnetic field 0–10 T . The degree of Ž . texture and transport critical current J of these films were enhanced by the application of a magnetic field. J increases c c with increasing magnetic field and the measured saturation magnetic field decreases with decreasing thickness of the film. This method provides for relatively rapid processing of highly textured Bi-2212rAg thick film or tape. q 1999 Elsevier Science B.V. All rights reserved.

Bi - 2212 r Ag tapes melt - grown under an elevated magnetic field ž / 0 – 10 T

Bi-2212rAg tapes with a thickness of 30 mm were melt-grown in elevated magnetic fields following two different thermal sequences. The transport critical current density, J dependence on the maximum processing temperature, cooling c rate, holding time and magnetic field was studied systematically. The quantity of impurity phase was decreased by reducing the holding time above the melting point o...

Dynamics of Transient Disordered Vortex States in Bi 2 Sr 2 Cacu 2 O 8+δ Typeset Using Revt E X 1

The dynamics of transient disordered vortex states in Bi 2 Sr 2 CaCu 2 O 8+δ was magneto-optically traced in three experiments: (i) during continuous injection of transient vortex states while ramping up the external magnetic field, (ii) during annealing of injected transient states while keeping the external field constant, and (iii) during annealing of transient 'supercooled' disordered state...

Absence of a proximity effect for a thin-films of a Bi2Se3 topological insulator grown on top of a Bi2Sr2CaCu2O(8+δ) cuprate superconductor.

Proximity-induced superconductivity in a 3D topological insulator represents a new avenue for observing zero-energy Majorana fermions inside vortex cores. Relatively small gaps and low transition temperatures of conventional s-wave superconductors put hard constraints on these experiments. Significantly larger gaps and higher transition temperatures in cuprate superconductors might be an attrac...

The gap anisotropy in Bi 2 Sr 2 CaCu 2 O 8+δ is revisited in the framework of a d-wave scenario in view of the recent angle-resolved photoemission experiment. Based on a tight-binding fit to the normal state dispersion, a detail analysis on the effects of the inclusion of the next harmonic in the d-wave has been presented. Significant effect has been observed in the superconducting T c. The den...
