摘　　要： 研究了快淬(Fe_(1-x)Ga_x)_(77.5)Nd_4 B_(18.5)合金的磁性,晶化行为,以及Ga含量和热处理对其硬磁性和相组成的影响,结果表明随着Ga含量x的增加,非晶态样品的Curie温度提高,而晶化温度降低,Fe原子的平均磁矩近似为一个常数,用X射线衍射和热磁测量分析了热处理后样品的结晶相,还研究了室温矫顽力与Ga含量的关系。 The Curie temperature increases but crystallization temperature decreases with the increase of Ga concentration, x, of amorphous (Fe_(1-x)Ga_x)_(77.5)Nd_4B_(18.5) alloys. The average magnetic moment of Fe atom is almost a constant. By X-ray diffraction and thermomagnetic measurements, the crystalline phases of the alloys, an unknown phase and α-(Fe, Ga) besides Fe_3B as major one, were identified. The room temperature coercive field with related to Ga con- centration was also studied.
