Development of Nd-Fe-B anisotropic bonded magnet with 27 MGOe

Synthesis and magnetic properties of hard magnetic (CoFe2O4)–soft magnetic (Fe3O4) nano-composite ceramics by SPS technology

“…Till now, many techniques, such as melt-spinning method, mechanical alloying method, hydrogenation-decomposition-desorption-recombination method, and Spark Plasma Sintering (SPS) method have been developed to synthesize the composite materials [15][16][17][18]. Among these methods SPS has been widely used in the preparation of dense ceramic materials, due to its rapidly sintering at high temperature under low atmospheric pressure.…”

Texture memory effect of Nd–Fe–B during hydrogen treatment

“…In the laboratory, a bonded magnet with 216 kJ m À3 has been produced [18]. The accomplished detailed knowledge of the ''texture memory effect (TME)'' should enable the realisation of further improved magnetic properties.…”

Residual Magnetic Flux Density Distribution Calculation Considering Effect of Aligning Field for Anisotropic Bonded NdFeB Magnets

“…On one hand, according to the manufacturing process, the NdFeB magnet can be classified into sintered and bonded types. On the other hand, according to the characteristics of magnet powders, it can be classified into isotropic and anisotropic ones [3][4][5]. Among different types of PMs, the anisotropic bonded NdFeB magnets are more attractive to the low power applications.…”
