- W2893772034 abstract "系统研究了室温下Tb0.3Dy0.6Pr0.1（Fe1-xAlx）1.95 （x=0.05，0.1，0.15，0.2，0.25，0.3）合金中元素Al替代Fe对结构、磁性、磁致伸缩性能和自旋重取向的影响.测量结果发现，x0.3Dy0.6Pr0.1（Fe1-xAlx）1.95合金基本上是纯的单相，x=0.2时出现其他杂相，杂相随Al替代量的增加不断增多.随Al替代量x的增加，点阵常数a接近于线性增大，Curie温度TC逐渐下降，而矫顽力Hc急剧下降.振动样品磁强计（VSM）测量发现，磁化强度M随Al替代量x的变化较为复杂.VSM计和磁致伸缩效应测量共同表明，少量Al的替代有利于降低磁晶各向异性，而且随着Al替代量x的增多磁致伸缩系数快速减小，x>0.15时巨磁致伸缩效应消失.穆斯堡尔效应研究发现，随Al含量的增加Tb0.3Dy0.6Pr0.1（Fe1-xAlx）1.95合金中易磁化轴可能在{110}面逐渐偏离了立方晶体的主对称轴，发生自旋重取向，从而引起合金宏观磁性、磁致伸缩性能的变化." @default.
