Abstract
It was found that the Ga addition to NdFeCoB magnets was very effective for improving their magnetic properties. Magnets with high boron concentration had a high coercive force and magnets with low boron concentration had a high‐energy product. The following magnetic properties were obtained: (1) Nd14.5FebalCo16Ga1B9.5:Br=12.0 kG, IHc=15.3 kOe, (BH)max=34 MGOe, Tc=500 °C (2) Nd14.5FebalCo16Ga1B5.5:Br=13.1 kG, IHc=12.2 kOe, (BH)max=40 MGOe, Tc=500 °C. It was also found that NdFeCoGaB magnets with very low boron concentration still had a relatively high coercive force.Keywords
