When the field is applied along the wires, the hysteresis loop exhibits a shear effect, which always means an equivalent demagnetizing field. It comes from the dipole interaction between the wires. The coercivity of the Fe nanowire arrays in the diameter of 16nm is 2000Oe at 300K, and it will increase to 2800Oe when the temperature decreases to 5K.

不同直径的Fe纳米线的磁滞回线均表明沿着线的方向均表现出shearing effect，表明其中存在一个等效退磁场，它来源于线间的偶极相互作用。16m的Fe纳米线的矫顽力室温下为2000Oe，5K时则达到2800Oe。

Increased spin disorder and a decrease of with increasing Fe content are evident. It depopulates the hopping electrons and weakens the double exchange. From resistivity and magnetization data, it is expected that the addition of Fe can introduce grain boundaries and form antiferromagnetic clusters.

电阻率的峰值随着Fe的增加而增大，并且峰值对应的温度TIM向低温移动，随着外加磁场的增大电阻下降，产生MR效应，这是因为随着掺杂的增加，自旋无序增加，外场的增加抑制了自旋的扰动，在顺磁温区内，电子自旋形成了随机的磁结构，产生电子局域，破坏了极化子形成的环境，因此输运机制由绝热极化子输运转变为变程跳跃机制。
