Magnetic nanostructure in an isotropic Nd-Fe-B bulk magnet was investigated using small-angle neutron scattering. The two-dimensional scattering patterns show the so-called spike anisotropy, which points the presence of a strong magnetodipolar interaction within the sample. The field-dependence of the scattering intensity is explained by a vortex-like flux closure structure. This suggests that magnetic vortices form pairs.
