One is that the hard magnet phase must bear intrinsic coercive force as high as possible. 一是要求硬磁相有尽可能高的内禀矫顽力和尽可能高的磁晶各向异性;
Intrinsic coercive force, iHc and energy product. ( BH)_ ( max) can be increased to about 48kA/ m and 16kJ/ m~ 3 respectively when compared with those of conventional 2: 17 rare earth alloy. 与常规的2:17稀土永磁合金相比,合金的矫顽力iHc和最大磁能积(BH)(max)分别提高48kA/m和16kJ/m~3左右。
