Structure and charge transfer correlated with oxygen content for a Y0.8Ca0.2Ba2Cu3Oy (y = 6.84–6.32) system: a positron study
TL;DR: In this article, the positron lifetime parameters of the Y0.8Ca0.2Ba2Cu3Oy system with a large range of oxygen content (y = 6.84 −6.32) were measured and the effect of ne and oxygen content on the structure, charge transfer and superconductivity was discussed.
Journal ArticleDOI
Local electronic structure, O–T phase transition and oxygen content in Y0.8Ca0.2Ba2Cu3Oy (y = 6.84 − 6.32) high-Tc superconductors
TL;DR: In this paper, the positron lifetime parameters have a strong dependence on oxygen content and show evident changes during orthorhombic-tetragonal phase transition ( y ǫ = 6.50 ± 0.05).
Journal ArticleDOI
Effect on superconductivity of high valence ions V4+ and Ni3+ substitution for Cu site in Pr1.85Ce0.15CuO4−δ system
TL;DR: In this article, the effects of high valence ions V 4+ and Ni 3+ substitution on superconductivity were studied systematically for the electron-doped superconducting Pr 1.85 Ce 0.15 CuO 4− δ (PCCO) system.
Proceedings ArticleDOI
Carrier Localization And Ion‐cluster Effect Affected By Oxygen Content For The Fe‐Doped YBCO Superconductors
TL;DR: In this article, the authors studied the Hall coefficient and superconductivity of the Fe-doped cuprate high-Tc superconducting YBa2Cu3−xFexOy (x=0, 0.1, 0,2) system.
Journal ArticleDOI
Local Electronic Structure, O–T Phase Transition and Superconductivity in the Ba-site Nd-substituted YBCO System
TL;DR: In this article, a series of YBa2−xNdxCu3Oy (x = 0.4) samples have been systematically studied by means of X-ray diffraction, transport property measurements and positron annihilation technology.
