The influence of post-growth short-term low-temperature annealings (O 2 , 400°C, 5–15 min) on the composition, crystal structure, and superconductivity of Bi 2 Sr 2 CaCu 2 O 8 + δ and Bi 2 Sr 2 CuO 6 + δ oxycuprate whiskers freely grown in gas cavities has been investigated...

The crystal structure of the insulating phase Bi2Sr2CuO6 is reported. The refinements were performed on X-ray and neutron powder diffraction data. The R values were Ri=10.56% (Rp=6.67%, Rwp=8.40%) for X-ray and Ri=7.4%(Rp=5.01%, Rwp=6.45%) for neutron data. The structure is ...
Effect of the oxygen content in ceramic high-temperature superconductors Bi 2Sr 2CuO 6 + delta on their phase composition, crystal structure, and charge state of cations has been studied. As the oxygen content changes, the lattice parameters were shown to exhibit nonmonotonic variation; no ...

For the sample treated in 8 T magnetic field, a clear second peak structure was observed in the magnetic hysteresis loop in the direction Hm∥Ha at 5 K, and the width of the hysteresis loop ΔM at 5 K and 0 T in the direction Hm∥Ha is about 10 times as large as that ...
electron diffraction reveal that, even though the extra oxygen behaviours in 0953-2048/11/5/006/img11 layers for the three samples are very different, they possess a similar monoclinic modulation characteristic with modulation wavelength 0953-2048/11/5/006/img12, which supports the crystal misfit ...
