The composition, crystallinity, uniformity, purity, and thermal stability of cuprate superconductors have been studied by Rutherford backscattering and channeling spectrometry, and 3.045 MeV He$^{+}$ oxygen non-Rutherford resonant scattering. Further

Among different techniques, electron crystallography presents the advantage to determine structures on a local scale or from very small samples. Different methods such as image processing, exit wave reconstruction, Patterson analysis, or direct metho

The layered high- T c related oxyborate NdBaCuO 2 BO 3 has been investigated by ED, HREM and neutron powder diffraction. The crystal structure was refined using neutron data (space group P4bm, Z =2, a =5.52807(5) A, c =7.44636(8) A; S =0.98, R p =0.0

CaO–CuO system has been investigated at high oxygen pressure. Only two ternary compounds, Ca 0.83 CuO 2 and Ca 14 Cu 24 O 41 , were found to be stable at P (O 2 )=500 bar. Ca 14 Cu 24 O 41 has been synthesized as a bulk phase for the first time. Th

We report a new reentrant superconducting-normal resistive transition observed in the Sr 1− x K x BiO 3 superconductor. Unlike the previous reports about the reentrant resistive transition where the superconducting region becomes reduced and finall

We have been able to synthesize a new bismuth-based oxide, SrBiO3, and to induce superconductivity by K doping performed under high pressure. Tc max is about 12K (for 45%–60% of K). These new compounds have a distorted perovskite-based structure. P

The so-called H phase in the system Li2O–TiO2 was prepared from niobia-doped R-Li2Ti3O7 (ramsdellite form) by reheating the quenched metastable R phase to 1000 K. The phase was characterized using transmission electron microscopy (TEM), powder X-ra

We report on the magnetotransport properties of the ${\mathrm{Tl}}_{2}{\mathrm{Mn}}_{2\ensuremath{-}x}{\mathrm{Ru}}_{x}{\mathrm{O}}_{7}$ pyrochlore as a function of the substitution degree $0l~xl~2.$ The evolution of the paramagnetic moment as a func
