This monograph provides the first extensive treatment of magnetic small-angle neutron scattering (SANS). The theoretical background required to compute magnetic SANS cross sections and correlation functions related to long-wavelength magnetization structures is laid out. The concepts are scrutinized based on the discussion of experimental neutron data. Regarding prior background knowledge, some familiarity with the basic magnetic interactions and phenomena as well as scattering theory is desired. Besides exposing the different origins of magnetic SANS, and furnishing the basics of the magnetic SANS technique in early chapters, a large part of the book is devoted to a comprehensive treatment of the continuum theory of micromagnetics, as it is relevant for the study of the elastic magnetic SANS cross section. Analytical expressions for the magnetization Fourier components allow to highlight the essential features of magnetic SANS and to analyze experimental data both in reciprocal, as well as in real space. Later chapters provide an overview on the magnetic SANS of nanoparticles and so-called complex systems (e.g., ferrofluids, magnetic steels, spin glasses and amorphous magnets). It is this subfield where major progress is expected to be made in the coming years, mainly via the increased usage of numerical micromagnetic simulations (Chapter 7), which is a very promising approach for the understanding of the magnetic SANS from systems exhibiting nanoscale spin inhomogeneity.

Reviews
An excellent book, providing an in-depth account of the combination of magnetic SANS with micromagnetic theory and a comprehensive overview of the progress made in relevant topics of mesoscale magnetism. * Sabrina Disch, Journal of Applied Crystallography *
A timely topic - the method of magnetic small angle scattering has now reached maturity and applications of the technique are numerous, such as the development of novel permanent magnets urgently needed e.g. for electric mobility. * Thomas Brueckel, Juelich Centre for Neutron Science JCNS and Peter Gruenberg Institute PGI, Germany *
A go-to manual for anyone doing a magnetic SANS experiment, well-structured and with a nice balance of the different relevant topics. * Diego Alba Venero, ISIS Neutron and Muon Source, Rutherford Appleton Laboratory, UK *
