Abstract

Abstract The temperature(T) dependence of the Knight shift(K) tensor at the 0(2,3) sites has been measured by the 17O-NMR in YBa 2Cu 3O 6+x with various oxidations (X=0.96, 0.8, 0.6, and 0.42). It has been found that the anisotropies in the Knight shifts along three principal directions are not dependent on both the temperature and the hole concentrations in the normal state and even in the superconducting(SC) state.
