## Elastic neutron ~ction experiments were performed on YBa2(Cu~.y ZnyhO6+x powders. Nuclear structures have been refined using the RieWeld method on powders of compositions x=l and y ranging from 0.0I to 0.06. The results suggest a solubility limit of zinc in the coper planes at y,,0.04 and zinc
The Nrel temperature TN of YBa2 (Cu~ \_rM~) aOr÷x for pure (0 < x < 0.3 ) and M = Zn and Ga doped samples (x< 0.2 ) has been measured from the abrupt increase of the s9y NMR width with decreasing T. A rather weak variation of TN and of the NMR width in the antiferromagnetic state has been detected u
