Magnetic Properties of Nd-Fe-B Anisotropic Magnets Prepared by Spark Plasma Sintering Method

Tetsuji Saito, Yusuke Sajima

Abstract

Nd-Fe-B hot-deformed magnets were produced by the spark plasma sintering (SPS) method from bulk materials prepared by the SPS method. The bulk materials, prepared by the SPS method from commercially available Nd-Fe-B melt-spun ribbon (MQ powder), consisted of the Nd2Fe14B phase and were magnetically isotropic. The subsequent hot deformation induced magnetic anisotropy in the Nd-Fe-B magnets. The optimally hot-deformed magnet showed a high remanence of 1.39 T with a maximum energy product of 240 kJm−3.
