Oxygen determination from cell dimensions in YBCO superconductors
نویسندگان
چکیده
A rapid and simple procedure for the determination of non-stoichiometric oxygen in YBa2Cu3O7 d (YBCO) superconductors is described, based on the relationship between oxygen content and c-axis parameter of the YBCO structure. To test the proposed method the oxygen content of samples sinterised starting from different precursors has been calculated from X-ray powder diffraction analysis and compared with the oxygen content obtained by iodometric titration with satisfactory correspondence. r 2004 Elsevier B.V.

Oxygen isotope effect in cuprates results from polaron-induced superconductivity
The planar oxygen isotope effect coefficient measured as a function of hole doping in the Prand La-doped YBa2Cu3O7 (YBCO) and the Ni-doped La1.85Sr0.15CuO4 (LSCO) superconductors quantitatively and qualitatively follows the form originally proposed by Kresin andWolf [Phys. Rev. B 49, 3652 (1994)], which was derived for polarons perpendicular to the superconducting planes. Interestingly, the inv...
متن کاملHeterostructures Based on High-temperature Superconducting Thin Films
For many possible electronic applications as well as fundamental studies it is essential to fabricate epitaxial layered structures of insulators, semiconductors or normal metals together with hightemperature superconductors (HTS). However HTS materials have complex lattice structures and this makes it difficult to grow multilayers with sharp interfaces preserving epitaxiallity through the whole...
متن کاملInfluence of Al doping and oxygenation on the superconducting properties of TSMG YBCO bulks
YBCO bulk single-grain samples with the nominal composition Y1.5Ba2(Cu1-xAlx)3Oy were fabricated by the Top – Seeded Melt – Growth process. Aluminium was found to be a suitable chemical dopant in Y1Ba2(Cu1-xAlx)3O7/Y2BaCuO5 bulk superconductors, which introduces effective nanosized pinning centres. An increase of the critical current density, Jc, and the appearance of a peak effect were observe...

In this paper, the effect of the cross-section on the critical current density (Jc) of a sample in ceramic superconductors YBa2Cu3O7-δ (YBCO) and Bi1.6Pb0.4Sr2Ca2cu3Oy (BPSCCO) has been studied. Five orthorhombic bar samples of YBCO with cross-sections of 6.25, 7.67, 9.25, 11.76, 14.67 mm2 and also five orthorhombic bar samples of BPSCCO with cross-section of 6.4, 9.01, 11.88, 13.86, 14.98 m...
متن کاملRelaxation and Thermal Conductivity of Hot and Thermal Quasiparticles and Fermi Liquid Interactions in d-wave Superconductors
In this paper, we calculate theoretically the relaxation rates of hot, thermal and antinodal quasiparticles by using Fermi’s golden rule. The transition probabilities at low temperatures express in terms of Bogoliubov coefficients, singlet and triplet scattering amplitudes and dimensionless Landau parameters. The values of Landau parameters may be determined by comparison with the experimental ...
