Neutron diffraction studies of permanent magnetic materials.

Neutron diffraction technology as an advanced material research technique has special advantages in studying magnetic materials compared to the conventional techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS). In this review, the applications of neutron diffraction technology on permanent magnetic materials were briefly reviewed: (1) the determination of the crystal structure and magnetic structure of the typical permanent magnet material, (2) in situ neutron diffraction study of the crystal structure evolution of the permanent magnets, and (3) phase transition in permanent magnetic materials.
