TL;DR: In this paper, the authors studied the evolution of the photoemission line shape as a function of momentum, temperature, and doping, and found that the peak-dip-hump structure arises from the interaction of electrons with a collective mode of wave vector (pi, pi).
Journal ArticleDOI
Preparation by dc single target sputtering and characterization of superconducting BiSrCaCuO films
TL;DR: BiSrCaCuO films (0.3 to 1.5 μm) were successfully prepared on MgO (100) substrate, using a simple dc single target sputtering system with pure Ar plasma, and post-deposition annealing.
Journal ArticleDOI
Anisotropy of superconducting properties of Bi-Sr-Ca-Cu-O thin films
TL;DR: In this article, the magnetic field dependence of the critical current was shown to be essentially dominated by the component of the magnetic fields perpendicular to the CuO 2 layers in the bismuth 2212 phase.
Journal ArticleDOI
Scaling behavior of the irreversible magnetization in epitaxial Bi2Sr2CaCu2O8 thin films
TL;DR: The scaling behavior of the hysteretic magnetization (or associated with it the critical current density) of high-quality epitaxial Bi 2 Sr 2 CaCu 2 O 8 thin films was studied in the temperature range 5-45 K and over three decades of the magnetic field H (50 G− 50 kG) as mentioned in this paper.
Journal ArticleDOI
GROWTH OF THE 110 K SUPERCONDUCTING PHASE AND CHARACTERIZATION OF Pb-doped Bi-Sr-Ca-Cu-O THIN FILMS PREPARED BY SPUTTERING
TL;DR: In this article, the authors reported on the preparation of (Bi- 1−x Pb x )-Sr-Ca-Cu-O thin films with T c up to 108K.
