Research Progresses of Preparation of Permanent Magnetic Materials by Spark Plasma Sintering

Spark plasma sintering (SPS) is a new kind of rapid sintering technology, which has been applied in studies on materials more and more. In this paper, the study progresses of preparation by SPS of permanent magnetic materials, including microncrystal, nanocrystal single phase and nanocomposite materials is overviewed, respectively.
