Neutron diffraction has been used to study antiferromagnetic ordering in YBa/sub 2/Cu/sub 3/O/sub 6+//sub x/ as a function of x. Evidence for such ordering has been observed only in the tetragonal, nonsuperconducting phase (xapprox. <0.4). The magnetic origin of the superlattice reflections has been confirmed with polarized beam measurements. A single antiferromagnetic structure was observed throughout the ordered phase, with a maximum Neel temperature approx.500 K and average ordered moment of (0.66 +- 0.07)..mu../sub B/ per magnetic Cu atom at xapprox. =0. Magnetic susceptibility measurements suggest that two-dimensional correlations are strong, as in La/sub 2/CuO/sub 4-//sub y/, and may survive into the orthorhombic phase.
