Electronic property and structure of double-doping Y1−2xPrxCaxBa2Cu3O7−δ with 0 ⩽ x ⩽ 0.14 by Yang Wang; Lei Shi; Songnan Chu is a Physics and Astronomy article available to read on EtoBox.
What is Electronic property and structure of double-doping Y1−2xPrxCaxBa2Cu3O7−δ with 0 ⩽ x ⩽ 0.14 about?
Equal amount Pr and Ca double-doping Y 1À2x Pr x Ca x Ba 2 Cu 3 O 7Àd with 0 6 x 6 0.14 have been investigated by X-ray diffraction, resistivity, and X-ray photoemission spectroscopy (XPS). The deviation of the linearly decreasing of T c vs. x curve was observed when x < 0.10. The resistivity and the temperature coefficient of resistivity also exhibit abnormal behaviors around x = 0.10. It is revealed that the conductivity behavior of Y 1À2x Pr x Ca x Ba 2 Cu 3 O 7Àd with low Pr content (x 0.10), which suggests a change of Pr valence with the Pr content. XPS measurement shows that the relative amount of Pr 3+ and Pr 4+ is closely related to the total Pr content x. The valence of Pr is close to +3 when x 0.10, which implies a different mechanism for depression of superconductivity of Pr content x 0.10 in Pr doping Y-123.
