چکیده انگلیسی
We have performed NQR measurement on the Cu(1) site in the CuO chain in Pr1âxYxBa2Cu3O7 in order to investigate how the charge density wave (CDW) state observed previously in the end compound PrBa2Cu3O7 develops in going metallic phase with increasing x. The Cu(1)-NQR evidence for the CDW transition, that is the unusual broadening of the NQR spectrum after the critical divergence of the nuclear spin echo decay rate and/or nuclear spin-lattice relaxation rate, was found to be confined in x â²Â 0.5 being essentially insulating phase in Pr1âxYxBa2Cu3O7. The disappearance of the CDW state is owing to a loss of perfect one-dimensionality in the CuO chain when the CuO2 plane becomes metallic.
