| 概要 | The in-plane normal-state resistivity of Zn-doped YBa2Cu3O7-delta Single crystals is measured down to low temperatures by suppressing superconductivity with magnetic fields up to 18 T. Substitution of Cu with Zn in the CuO2 planes is found to induce carrier localization at low temperatures in "clean" samples with k(F)l >5, where the mean free path l is larger than the electron wavelength and thus localization is not normally expected. The destruction of the local antiferromagnetic correlation among Cu spins by Zn is discussed to be the possible origin of this unusual charge localization. |
