چکیده

Magnetization curves habe been measured on YBa2Cu307-, single crystals of various size, and compared with other results published in the literature. The irreversible magnetization does not follow the scaling law predicted by the Bean model. We conclude that even the superconducting crystals contain normal barriers or weak links which limit the spatial scale of supercurrents.

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...

Oscillatory dynamics and organization of the vortex solid in YBa2Cu3o7 single crystals.

We report on the degree of order of the vortex solid in YBa2Cu3O7 single crystals observed in ac susceptibility measurements. We show that when vortices are "shaken" by a temporarily symmetric ac field they are driven into an easy-to-move, ordered structure but, on the contrary, when the ac field is temporarily asymmetric, they are driven into a more pinned disordered state. This is characteris...

ساختار و خواص ابررسانای YBa2Cu3O7-δ آلاییده با کادمیوم اکسید توده

In this paper, the Y1-xCdxBa2Cu3O7-δ superconductor with x=0, 0.05, 0.1, 0.15, 0.2, 0.3, 0.4, 0.5 are prepared using the solid state method and the structure, electrical resistance, critical current density and critical temperature of it, have been studied. The results show that these doping do not affect so much on the structure and lattice parameters. The electrical resistance of samples incr...
