Activity and diffusivity of oxygen in a liquid Yb1Ba2Cu3 high temperature superconducting precursor alloy
TL;DR: The activity and diffusivity of oxygen in a liquid Yb1Ba2Cu3 high temperature superconducting precursor alloy have been measured by modified coulometric titration method in a temperature range from 913 to 957°C as mentioned in this paper.
Journal ArticleDOI
Photoinduced hole-doping effect in (Y0.5Ca0.5)Ba2Cu3Oδ films
TL;DR: In this paper, the effects of photoinduced changes in the critical temperature and the normal state conductivity of (Y 0.5Ca0.5)Ba2Cu3Oδ thin films are studied.
Book ChapterDOI

Maw-Kuen Wu,J. R. Ashburn,C. J. Torng,Pei-Herng Hor,R. L. Meng,Li Gao,Z. J. Huang,Yongmei Wang,Ching-Wu Chu +8 more
TL;DR: In this paper, a stable and reproducible superconductivity transition between 80 and 93 K has been unambiguously observed both resistively and magnetically in a new Y-Ba-Cu-O compound system at ambient pressure.
Journal ArticleDOI
Synthesis of YBa2Cu3O7 and YBa2Cu4O8 superconductors via carbonate coprecipitation
D.H. Chen,T.W. Liu,J.C. Huang,Chien-Hong Cheng,Chau-Ting Chang,S.R. Sheen,T.C. Wang,Maw-Kuen Wu +7 more
TL;DR: In this article, coprecipitation using triethylammonium carbonate (Et 3 HN) 2 CO 3 ) as precipitant was used to prepare the YBa 2 Cu 3 O 7 (Y 1-2-3) and Y Ba 2 Cu 4 O 8 (Y 2-4) high-T c superconductive materials.
Journal ArticleDOI
Observation of iron d-orbitals modifications in superconducting FeSe by Raman spectra study
H.-I. Hsiung,H.-I. Hsiung,W.H. Chao,H.Y. Hsu,Ming-Jye Wang,Hsiang Lin Liu,Maw-Kuen Wu,Maw-Kuen Wu +7 more
TL;DR: In this paper, the authors studied the Raman spectra of superconducting FeSe and non-superconducting Cu-doped FeSe crystals at different temperatures, showing that the dzx and dyz orbitals of Fe split at ∼130 K and then become closer to achieve balance as temperature decreases.
