The late first row transition metal monoxides are the canonical antiferromagnets. Their magnetic structures were first determined many decades ago but contemporary studies have unearthed a wealth of unexpected physics in these oxides. Our total scattering studies have shown they adopt more complex magnetic structures, suggestive of magnetic modulations, revealing that previous studies painted far too simple a picture of their magnetic ordering. Since these are the fundamental compounds from which much of our knowledge of magnetism is built a detailed understanding of their antiferromagnetic states is vital. Preliminary studies of MnO using the unique high resolution of WISH, confirm the presence of magnetic modulations and we are in a unique position to extend this to a precise determination of the magnetic structures of NiO and CoO, to resolve questions regarding these canonical oxides.
