摘要：
We have studied the effects of Ga substitution for Fe in the crystallization and on the magnetic properties of Nd4Fe78-xGaxB18 (x = 0.5, 1.0, 1.5 or 2.0) composites. The remanence and coercivity were improved with the addition of 0.5% atom-Ga. Field annealing was found to enhance slightly the remanence. (C) 1999 Elsevier Science B.V. All rights reserved.
