Polarization-dependent X-ray absorption spectroscopy of in-plane aligned (100) YBa2Cu3O7 d thin films

چکیده
Polarization-dependent X-ray absorption spectra (XAS) on the O 1s edge has been measured on a highly in-plane aligned (1 0 0) a-axis YBa2Cu3O7 d (YBCO) thin films. The in-plane XAS, that is, the electric field E of the linearly polarized synchrotron light parallels to bor c-axes of YBCO films (Ekb or Ekc), were obtained in a normal-incidence alignment. Furthermore, the XAS for Eka was calculated from the oblique incidence to the sample with different angles. The present results are consistent with those obtained by using detwinned YBCO single crystals. 2003 Elsevier Science B.V. All rights reserved.

X-ray absorption spectroscopy study of the local structures of crystalline Zn–In–Sn oxide thin films
The local structure of a Zn, Sn codoped In2O3 thin film grown on ĉ-plane sapphire by pulsed-laser deposition was examined by polarization-dependent x-ray absorption spectroscopy. The bixbyite film structure is both out-of-plane and in-plane oriented, and the structural results show that both Zn and Sn dopants occupy In sites. The In–O bond length is comparable to that in powder In2O3. However, ...

In this study the effect of crystallite size reduction and microstructure on the electrochemical corrosion behavior of nanocrystalline nickel (NC Ni) were investigated using Tafel polarization and electrochemical impedance spectroscopy (EIS) measurements in 10 wt.% NaOH. NC Ni coatings were produced by direct current electrodeposition using chloride baths in presence and absence of saccharin as...
متن کاملEffect of Cobalt Concentration on Structural and Magnetic Properties of Co-Fe Thin Films
Co-Fe films were electrodeposited on Cu substrate from electrolytes with different Co concentration levels. X-ray diffraction (XRD) was used to investigate the films crystal structures. The results indicate that if the Co concentration is less that the Fe concentration, the cubic structure appears in the films, while the hexagonal structure dominates when the C...
