磁化

Our works discuss the magnetic characteristics of wasp-waisted hysteresis loops and outline a rationale for this type of behavior by superposition of hard and soft magnetic phases. Because of the absence of magnetic interactions between particles, in measurement procedure, we could sum the magnetization mathematically of the isolated particles at each field value to create a composite hysteresis loops.

进一步再以复合模型磁相叠加的特性，以考虑忽略软硬磁晶粒间彼此交互作用的前提下，将软磁与硬磁的磁滞曲线以线性叠加得到不同磁场强度下各材料的磁化强度以描绘出该复合模型的磁滞曲线，并发现磁相叠加与实际量测的磁滞曲线虽相近但仍有其差异，而其差异则系由於软硬磁混合样品中其晶粒间仍有交互作用之存在。

非晶材料的尖锐脉冲电压现象是由于具有显著的不可逆壁移磁化过程导致大巴克豪森跳跃所造成的，脉冲的尖锐性与动态磁滞回线的形态密切相关，回线的方形度越高，则脉冲愈尖锐。

The results show that with the increase of deformation strains and thinning of Fe-Cr fibers, the saturation magnetization are about 140 A·m2/kg constantly, and the remanent magnetism and coercivity increase gradually.The magnetic properties of Fe-Cr fibers are invariant when the Fe-Cr fibers were preserved in absolute alcohol or air for more than 1 a. After Fe-Cr fibers heated in air at temperature higher than 300 ℃ for 1 h, the Fe-Cr fibers transform from ferromagnetic α-solution to paramagnetic2O3, and the saturation magnetization of samples decreases remarkably. With the increase of deformation strains, the thermal stability of thinner Fe-Cr fibers decreases.

结果表明：随着变形量的增大和Fe-Cr纤维的细化，纤维的饱和磁矩基本恒定(约140 A·m2/kg)，而剩磁和矫顽力则逐渐增加； Fe-Cr纤维在无水乙醇和空气中储存一年以上，磁性基本保持不变； Fe-Cr纤维在空气中经300 ℃以上加热1 h后，逐渐由铁磁性的α-固溶体转变为顺磁性的2O3，饱和磁化强度显著下降；且随着变形量的增大，较细Fe-Cr纤维的热稳定性较差。
