Nanocompositional Electron Microscopic Analysis and Role of Grain Boundary Phase of Isotropically Oriented Nd-Fe-B Magnets

Table 3

Measured Fe + Co content in GBs in sintered and melt-spun Nd-Fe-B magnets and resulting magnetic properties.

	Measured Fe + Co [at%]	[T]	[pJ/m]
-GB (sintered)	40	0.15	0.12
-GB (sintered)	75	1.00	5.41
MQU-F	55	0.43	1.00
MQP-B+	79	1.10	6.54

After Sakuma et al. [40], is proportional to [41]. [11].
