Abstract

We have carried out high resolution neutron powder diffraction experiments aiming at a determination of the magnetic structure of the S=1/2 layer compound NaNiO₂. The magnetic moments are ferromagnetically aligned in the NiO₂ layers and antiparallel between layers. The direction of the magnetic moment has a small component along the a-direction.
