[en] The effects of static- and rotating-magnetic-field annealing on the magnetic softness and the magnetization alignments in nanocrystalline Fe84Nb6B10 have been investigated by means of DC magnetometry and small-angle neutron scattering (SANS). At the remanent state, the SANS pattern obtained from the static-field annealed sample exhibited an enhanced SANS signal in the direction normal to the uniaxial anisotropy (Ku) field direction, indicating a well-developed long-range magnetization alignment along the direction of Ku. Contrarily, the SANS pattern for the rotating-field annealed sample is virtually isotropic at zero field, reflecting the lack of anisotropic magnetization alignments. The soft magnetic properties of nanocrystalline Fe84Nb6B10 are improved dramatically by rotating-field annealing due to the suppression of Ku.
