D-HOLE LOCALIZATION AND THE SUPPRESSION OF SUPERCONDUCTIVITY IN AN YBACUO CERAMICS WITH SUBSTITUTION OF X COPPER FOR ZINC.

Author(s) : JEE C. S., et al.

Type of article: Article

Summary

THE TEMPERATURE AND ZINC CONCENTRATION DEPENDENCE OF THE ELECTRICAL RESISTIVITY, SPECIFIC HEAT, MAGNETIC SUSCEPTIBILITY, AND ELECTRON PARAMAGNETIC RESONANCE (EPR) SPECTRA OF THIS CERAMICS HAS BEEN MEASURED FOR X NOT HIGHER THAN 0.16. THE FIELD DEPENDENCE OF THE MAGNETIZATION HAS BEEN MEASURED FOR THE TEMPERATURE RANGE 2-300 K AND FIELDS POSITIVE AND LOWER THAN 9.0 T. THE SUBSTITUTION OF ZINC FOR COPPER CAUSES A RAPID AND NEARLY LINEAR DEPRESSION OF THE SUPERCONDUCTING TRANSITION TEMPERATURE. THE ELECTRICAL RESISTIVITY, MAGNETIC SUSCEPTIBILITY, EPR SPECTRA, AND SPECIFIC HEAT ALL INDICATE THAT THE D-HOLES ASSOCIATED WITH THE COPPER IONS BECOME LOCALIZED IN THE NONSUPERCONDUCTING PHASE, FOR X HIGHER OR EQUAL TO 0.10.
