Test and Evaluation Department, Technical Center Asia Motors Co. Inc., 500-250, Kwangju, Korea aut The doping effects on the critical temperature of high-temperature superconductors [Elektronische Daten] [Kang Jung] X-ray diffraction, dc magnetization, and electrical resistance have been measured for several high-temperature superconductors at temperatures between 18 and 295K. The dc magnetization and electrical resistance measurements showed almost the same trends for basic YBCO and Dy-doped YBCO superconducting materials. Tc was about 92K for both the samples. These results indicates that the electronic structures are different at temperatures above and below Tc and the electron density is higher in superconducting state than in normal state. The PBCO compound was an insulator with little defects structure. The hole filling or hole localization mechanism was proposed for the decrease in Tc with an increase in Pr content.
