Structure of (CuO)2 double layers in superconducting YBa2Cu3O7

New analytical soliton type solutions for double layers structure model of extended KdV equation

In this present study the double layers structure model of extended Korteweg-de Vries(K-dV) equation will be obtained with the help of the reductive perturbation method, which admits a double layer structure in current plasma model. Then by using of new analytical method we obtain the new exact solitary wave solutions of this equation. Double layer is a structure in plasma and consists of two p...

the role of thematic structure in comprehending spoken language

in fact this study is concerned with the relationship between the variation in thematice structure and the comprehension of spoken language. so the study focused on the following questions: 1. is there any relationship between thematic structure and the comprehension of spoken language? 2. which of the themes would have greated thematic force and be easier for the subjects to comprehend? accord...

Effect of Sintering Conditions on Microstructure and the Superconducting Properties of YBa2Cu3O7 x

YBa2Cu3O7-X tapes fabricated from precursor powder, were used to investigate the effect of sintering conditions on the microstructure. The sintering experiments were carried out in oxygen over the temperature range of 915-950ْC. Scanning electron microscopy was used to examine the sintered products. The result indicated a significant increase in densification and grain growth when the tapes were...

Current-driven vortex dynamics in untwinned YBa2Cu3O7 superconducting single crystals

Current-driven vortex dynamics of type-II superconductors in the weak-pinning limit is investigated by quantitatively studying the current-dependent vortex dissipation of an untwinned YBa2Cu3O7 single crystal. For applied current densities (J ) substantially larger than the critical current density (Jc), non-linear resistive peaks appear below the thermodynamic firstorder vortex-lattice melting...
