We have employed polarized and unpolarized neutron-diffraction techniques on both powders and single crystals to establish the nature of the magnetic order of the Cu ions in oxygen deficient (non-superconducting) RBa/sub 2/Cu/sub 3/O/sub 6/..mu../sub x/ (R = Y, Nd). Magnetic Bragg peaks of the type (h2,k2,l) are observed, which yield a magnetic structure in which the Cu spins are coupled antiferromagnetically both in the Cu-O planes as well as along the tetragonal c axis, with the spin direction in the tetragonal plane. The Neel temperature is very sensitive to the oxygen content, with T/sub N//sub (//sub x//sub approx.//sub 0)/approx. =500 K, while the spin configuraton is independent of x.
