Site Assignment for Cu NQR Lines in YBa2Cu3O7-δ Superconductor
Abstract
A clear evidence is presented on the site assignment for two distinct 63 Cu NQR lines observed at around 22 MHz and 31 MHz in YBa 2 Cu 3 O 7-δ superconductor ( T c =91 K). Using the highly oriented powder sample under the applied magnetic field in the superconducting state where the c -axis being perpendicular to the field, the 63 Cu NMR spectra have carefully been examined. From analysis of the spectra, the directions of the principal axes of …
