Abstract
The controlled nanocrystallization of Nd-Fe-Co-Al-B bulk amorphous tunes the coercivity, which is enhanced to 23Â kOe, with a Curie temperature of 692Â K. Ferromagnetic Nd2(Fe,Co,Al)14B nanocrystallites isolated by amorphous clusters coexist with antiferromagnetic Nd6(Fe,Co,Al)14. These magnetic properties are examined by the combination of X-ray diffraction, high-resolution transmission electron microscopy, magnetization measurements, and Mossbauer spectrometry. The grain size for optimal magnetic properties is around 40Â nm.
