The (001) surface of NiO, an antiferromagnet at room temperature, was investigated under ultrahigh vacuum conditions with frequency modulation atomic force microscopy. The antiferromagnetic coupling between ions leads to a spin superstructure on (001) surfaces. Exchange interaction between the probe of a force microscope and the NiO (001) surface should allow us to image spin superstructures in ...
