| Term | Definition |
|---|---|
| Remanence (Br) | Residual magnetic flux density after removing the external field. |
| Intrinsic coercivity (Hcj) | Field strength required to reduce magnetization to zero. |
| BHmax | Maximum amount of magnetic energy stored in a magnet. |
| Working temperature (Tw) | Highest temperature at which a magnet operates while maintaining its performance. |
| Curie temperature (Tc) | Point above which a ferromagnetic material becomes paramagnetic. |
| Grain boundary diffusion (GBD) | Process where Dy/Tb diffuse along grain boundaries to improve coercivity. |
| Sintering | Heat treatment at ~1100°C that densifies compacted powder into a solid body. |
| VCM | Voice coil motor, used in hard drives and camera autofocus. |
| PMG | Permanent magnet generator, used in direct-drive wind turbines. |
