The scattering cross-sections of a polarised neutron beam, incident on a magnetic sample, are a function of the polarisation of the beam, and of the nuclear and magnetic structure of the sample. An analysis of the polarisation of the scattered neutrons is valuable in isolating magnetic contributions.
The spin distribution, obtained by Fourier inversion of the magnetic structure factors calculated from the cross-sections, has been studied in ferromagnetic metals, intermetallic compounds and alloys. Applications of the method to the study of anti-ferromagnets and canted ferromagnets are outlined. Paramagnetic metals, solid organic radicals and transuranium elements have spin distributions in which orbital and other effects can be compared with theory.
The value of polarisation analysis and some of the new technical developments which have made it possible are described. Applications to inelastic phenomena are mentioned.
