Abstract

Magnetic properties and structures of low rare-earth content (Nd=2-7at.%) α-Fe/Nd<SUB>2</SUB>e<SUB>14</SUB>B type Nd-Fe-Co-V-B system bulk exchange-spring magnets prepared by the Spark Plasma Sintering (SPS) method were investigated. In this range of Nd content, the bulk magnets showed the same magnetic properties as those of the annealed ribbons used as the raw materials. The saturation magnetization and soft/hard phase ratio corresponded with the estimated values. However, the exchange coupling strength decreased conspicuously with a lower Nd content presumably as a result of an increase in the grain size.
