Structural properties of indium doped YBa₂Cu₃O₇-x high Tc superconductors

Creator:

Weidlich, Georg A.

Abstract:

YBa₂Cu₃0₇₋x was doped with In by a stoichiometrically exact substitution of Y by In, doping levels ranging from 0% to 20%. Room temperature X-ray diffraction measurements, Perturbed Angular Correlation spectroscopy using ¹¹¹Cd as nuclear tracer at a variety of temperatures ranging from room temperature to 950°C and magnetic flux exclusion...

Perturbed angular correlation spectroscopy of oxide ceramics at high temperature

Creator:

Su, Han-tzong

Abstract:

Perturbed angular correlation (PAC) spectroscopy of dilute zirconia alloys and YBa₂Cu₃0₇₋x, ceramic superconductors at elevated temperature have been measured using ¹¹¹Cd as the probe. The oxygen vacancy concentration in the zirconia samples was controlled by doping with yttrium or indium, which introduce vacancies, or with niobium, which removes vacancies. A...
