Small-angle neutron scattering (SANS) is a powerful technique for the investigation of magnetic materials, since it provides information from within the bulk of magnetic media and on the mesoscopic length scale, i.e., the size regime between a few nanometers and a few micrometers. In this talk we give an introduction into the basics of magnetic SANS and we summarize recent theoretical and experimental work. This includes the study of the effect of the Dzyaloshinskii-Moriya interaction in microstructural-defect-rich materials, invstigations of the spin structure of Nd-Fe-B nanocomposites and Mn-Bi magnets, and the usage of micromagnetic simulations for understanding the spin structure of nanoparticles beyond the single-domain form-factor concept.
