^63,65Cu NMR study of the antiferromagnet CuCrO₂

Abstract

The 63,65Cu NMR and NQR spectra have been obtained in single crystal sample of CuCrO2 in the magnetically ordered phase. The components of the electric field gradient tensor (EFG) characterizing the structure of the nearest environment of copper ions are determined from the analysis of the spectra. Comparative analysis obtained data with similar data of paramagnetic phase showed that the local charge environment of copper nuclei does not change during the magnetic phase transition.
