Neutron-diffraction techniques have been used to study the magnetic ordering of the Nd ions in semiconducting Nd{sub 2}CuO{sub 4} and superconducting Nd{sub 1.85}Ce{sub 0.15}CuO{sub 4}. For the Ce-doped system a sharp transition to long-range antiferromagnetic order occurs at {ital T}{sub {ital N}}{approx}1.2 K, with a simple magnetic unit cell which is double the chemical unit cell along the {ital a} and {ital b} directions. The same magnetic structure is observed in the parent system Nd{sub 2}CuO{sub 4}, in which the Cu spins are also ordered magnetically, but strong coupling between the Nd and Cu sublattices is indicated.
