Inducing anisotropy in bulk Nd-Fe-Co-Al-B nanocrystalline alloys by quenching in magnetic field

► Inducing anisotropy in bulk nanocrystalline alloys by quenching in magnetic field. ► Magnitude of the induced anisotropy is enhanced by Co-concentration. ► Nd2(Fe,Co)14B stick-like nanograins is main factor for anisotropy of the alloys. ► Bulk Nd-Co-Fe-Al-B nanocrystalline alloys fabricated by rapid solidification. ► High coercivities up to 1.6 T achieved in bulk Nd-Co-Fe-Al-B nanocrystalline alloys.
