The technique of small angle neutron scattering (SANS) furnishes unique information on the length scale and local magnetic anisotropy at the nanoscale in nanocomposite ferromagnets. Such information is not presently available using any other microscopic technique. The basic principles and results of the SANS technique will be presented with regard to a unique and unexpected observation of a dipole field controlled spin disorder in a nanocomposite ferromagnet, FeZrBCu, which consists of bcc Fe particles embedded in a magnetically active amorphous matrix.
