Small‐angle neutron scattering (SANS) has been used to investigate the onset of magnetic order and some aspects of the magnetic microstructure in a series of bulk amorphous rare‐earth iron alloys prepared by DC rapid sputtering. SANS was also used to investigate crystalline (but atomically disordered) TbFe 1.5 Al 0.5 and crystalline TbFe 2 . The measurements were made for the most part on a two‐axis spectrometer at a wavelength λ =2.4 Å with collimations of 20′–10′–10′. Some measurements were made on a three‐axis spectrometer to obtain information on the inelasticity of the scattering.
