Neutron diffraction measurements have been taken on single crystals of NdBa/sub 2/Cu/sub 3/O/sub 6/..mu../sub x/ to explore the nature of the magnetic order as a function of oxygen concentration x. The Cu-O planes are known to order antiferromagnetically at T/sub N1/, with T/sub N1/(xapprox. =0)approx. =450 K. At lower temperatures we find that the oxygen-deficient Cu planes also order magnetically (T/sub N2/(xapprox. =0.1)approx. =80 K), with a large ordered moment of 0.46..mu../sub B/ and a simple antiferromagnetic sequencing along the c axis. Both ordering temperatures decrease with increasing x, with T/sub N2/ being much more sensitive to x than T/sub N1/.
