Fascinating current density features of noble metal doped YBa2Cu3O7-δ (YBCO) Superconducting materials

Abstract

The aligned YBa2Cu3O7-δ(YBCO) superconducting materials were prepared by unique annealing method on a Gold foil. The structural and other properties of these superconducting materials have been studied i.e. X-ray diffraction, Scanning Electron Micrograph Magnetization and resistivity measurements. The study shows that the change in the Gold doping concentration in these superconducting materials from 0.1 to 3% affected the transition temperature range from 89K to 94K and the critical current density noticeably. The current density measured from the M-H curve is 2 × 104 Acm-2 by Bean Model. Densification and elongated alignment ≈200 µm longs are observed in these materials.
