Neutron scattering experiments on single crystals have allowed an accurate determination of the magnetic phase diagram of YBa,Cu,O,,,. For increasing oxygen content the antiferromagnetic ordering of YBa,Cu,O, is unchanged up to x = 0.2. For x > 0.2 both TN and the ordered moment of Cu" ions in the
63Cu( 1 ) NQR signals and their relaxation have been measured in YBa2Cu306.1 and ErBa2CuaO6+x at temperatures between 10 K and 300 K. In YBa2Cu306.1 a peak is observed in the spin-lattice relaxation, T/-~, around 140 K. An explanation in terms of doped-hole motion is presented and alternative O (4)-
