用粉末中子衍射研究了MnO、FeO、CoO和NiO的反铁磁磁矩排列。四种氧化物的结果与磁矩排列在平行于（111）面的铁磁片中并且相邻面中的磁化方向反平行的结构一致。中子漫散射的观测限制了确定磁化方向的精度。如果布拉格散射包括漫射强度，MnO和NiO的磁化方向位于（111）平面内;对于CoO，优选方向是[117]，在（111）平面和四轴之间。FeO中的磁轴垂直于铁磁片。
The antiferromagnetic arrangement of moments in MnO, FeO, CoO, and NiO have been investigated by powder neutron diffraction. The results for the four oxides are consistent with a structure in which the magnetic moments are arrayed in ferromagnetic sheets parallel to (111) planes, and the direction of magnetization in neighboring planes is antiparallel. The observation of diffuse neutron scattering limits the precision with which the magnetization direction can be specified. If the diffuse intensity is included with the Bragg scattering, the direction of magnetization in MnO, and NiO lies within the (111) plane; for CoO, the preferred direction is [1 1 7], intermediate to the (111) plane and the tetragonal axis. The magnetic axis in FeO is perpendicular to the ferromagnetic sheet.
