Characterization of High-Temperature Superconducting Materials in Y-Ba-Cu-0 Systems

Abstract

The Y-Ba-Cu-0 systems have been reported to be a high temprature superconductor with above 90K. Optical Study would give us useful informations as a characterization for Y-Ba-Cu-0 systems with an analysis of energy dispersive X-ray system EDS. Optical constants of superconducting Y-Ba-Cu-0 systems are n*=1.6 92-j0.403 for 99.99%(4N) with Y1.00 Bal.90 Cu2.87 and n*=1.604-j 0.441 for 99.99%+ (4N+) with Y1.00 Ba2.18 Cu3.12.
