| Popis: | 89 Y-NMR linewidth and relaxation rate data are reported for YBa 2 Cu 3 O 7−δ in the orthorhombic metallic and the tetragonal nonmetallic modifications. The temperature dependence of the observed relaxation rates is Korringa like with almost equal Korringa constants for both compounds. These results are correlated to the Cu(2) NMR data of Warren et al. and might be seen as a support of any theory which decouples charge transport from spin fluctuations. |
