Relationship Among Preparation, Structure and Superconductivity in Ti-Ca-Ba-Cu-O Compounds

Abstract

Analysis of a comprehensive set of experimental results has proven the substantial effect of the precise preparation conditions upon the structure and superconducting parameters of Ti-Ca-Ba-Cu-O samples. The techniques required for the preparation of specimens of single phase and long-term stability, together with methods for improvement of the characteristic parameters have been determined. Comparing results derived from samples prepared by different methods has allowed the quantitative differences of the characteristic parameters to be evaluated.
