Correlation-induced Suppression of Bilayer Splitting in High-T c Cuprates: A Variational Cluster Approach
We carry out a theoretical study of the bilayer single-band Hubbard model in the undoped and in the superconducting phases by means of the...

Electronic Density of States and Strong Electron–Phonon Coupling in Nb3Sn
Using the Full-Potential non-orthogonal Local-Orbital Minimum-Basis Band-structure Scheme (FPLO) coupled with the XFSF program for unconventional...

Epitaxial growth of solution deposited Bi\(_\mathsf{2}\)Sr\(_\mathsf{2}\)CaCu\(_\mathsf{2}\)O\(_\mathsf{x}\) films
The epitaxial growth of Bi 2 Sr 2 CaCu 2 O x (Bi2212) high temperature superconducting thin films was studied. The films were solution-deposited from a...

Insulator-metal transition in the single-crystal high-T c superconductor Bi-2201
Variations in the temperature behavior of resistivity, ρ ( T ), in the ab plane of the anisotropic single-crystal high- T c superconductor BiSrCuO (2201...

The Effects of Substitution of Sn for Cu in Bi1.75Pb0.25Sr2CaCu2.3−x Sn x Sn x O y
The influence of Sn do** on superconductivity in the Bi-based 2212 phase is studied in this paper. For the samples R–T relations and magnetic...

Magnetic scattering, “recovery” of superconductivity and tunneling in the cuprates
High T C cuprates contain various magnetic scatterers. Their presence affects many features of the materials, including tunneling density ofstates....

Measurements ofH c2(T) in Bi-Sr-Cu-O
H c 2 ( T ) has been measured for thin BSCO films at temperatures down to 65 mK and pulsed fields up to 35 T. H c 2 ( T ) diverged anomalously as the...

Superconducting Multi-layers of Bi2Sr2CaCu2Oy/Bi2Sr2CuOx Grown by RF Magnetron Sputtering
Superconducting Bi2Sr2CaCu2Oy(BSCCO) and normal conducting Bi2Sr2CuOx(BSCO) thin films were multi-layered using a multi-target RF magnetron... -
Preparation and Patterning of Bi-System 2-2-1-2 Phase by Ca Diffusion into 2-2-0-1 Single Crystals
Preparation of the Bi-system 2212 phase area was carried out by partial recrystallization with Ca-diffusion into 2201 single crystals for the first... -
Electron Tunneling and Acoustic Mode in High-Tc Superconductors
We show that the electron-hole liquid model can explain some of the anomalous features found in the tunneling conductivity for NIS-junctions. The... -
X-ray diffraction analysis and occurrence of multiple phases in Bi-Sr-Ca-Cu-O superconductors
Starting composition 1112 for Bi-Sr-Ca-Cu-oxide yields multiphase super-conductors with the proportion of constituent phases depending sensitively on...
