The Role of Mass of Doped Atoms in the Superconductivity of Cu 0.5 Tl 0.5 Ba 2 Ca 2 Cu 3 O 10−d and Cu 0.5 Tl 0.5 Ba 2 Ca 2 Cu 1.5 M 1.5 O 10−d ( M = Cd, Zn, and Ni)
TL;DR: In this paper, the authors have synthesized Cu0.5Tl 0.5Ba2Ca2Cu3O10−d (M = Cd, Zn, and Ni) samples by two-step solid-state reaction method at 860°C.
Journal ArticleDOI

M. Usman Muzaffar,Syed Hamza Safeer,Nawazish A. Khan,Aqeel A. Khurram,Tayyab Subhani,Rabia Nazir +5 more
TL;DR: In this article, the superconducting properties of Cu0.5Tl 0.5 Ba2Ca3Cu4O12−x were studied after the inclusion of ZnO nanoparticles.
Journal ArticleDOI
Excess Conductivity Analysis of Cu 0.5 Tl 0.5 Ba 2 Ca n−1 Cu n O 2n+4−δ ( n = 2, 3, 4) Thin Films
TL;DR: In this paper, the Ginzburg-Landau theory was employed to calculate important superconductivity parameters, such as the flux pinning characters and the inter-layer coupling of CuO2 planes.
Journal ArticleDOI
Effect of Magnesium Doping to Reduce the Charge Reservoir Layer in Cu 0.5 Tl 0.5 (Ba 2−x Mg x )Ca 2 Cu 3 O y ( x = 0, 0.15, 0.25, 0.35) Superconductors
TL;DR: In this paper, the effect of reducing the thickness of the Cu0.5Tl 0.5-1223 crystal has been studied, in which the c-axis lattice parameter and unit cell volume were systematically suppressed with increasing incorporation of Mg into the final compound, thereby resulting in suppression of the charge reservoir.
Journal ArticleDOI
Study of Carrier Transfer Mechanism When Substituting Strontium at Barium Sites in CuTl-1223 Superconducting Phase
TL;DR: In this article, the effect of doping strontium atoms on the intrinsic superconductor parameters of these samples was studied by excess conductivity analysis, which revealed that the coherence length along the c-axis, the interlayer coupling, and the Fermi velocity of the carriers increased for the Sr doping levels of x = 0.1 and 0.2 but decreased for the sample with x à = à 0.3.
