Dy2O3

Diffusing Effects of Sintered NdFeB Magnets The DyZn film on sintered NdFeB magnet surface was prepared through DC magnetron sputtering. The magnetic properties, thermal stability and microstructure of annealed and DyZn diffused magnets were compared. The coercivity enhances significantly from 1174.10kA/m to 1711.40kA/m by a striking increment of 45.7% with only a slight reduction in [...]
