各向异性

Unexpectedly the vanishing magnetic cubic anisotropy in Permalloy is found to be independent of its atomic structure but depends only upon the stoichiometry of Fe and Ni in the Fe_x Ni_(1-x) alloy. This new observation is further investigated and confirmed by first principles electronic band calculations, which helps to understand the long-standing issue why Permalloy should be a soft magnet.

我们发现立方磁晶各向异性能(K_1)消失这个Permalloy的软磁特性跟具体晶体结构无关，只取决于化学组分，第一性原理能带计算也验证了这一实验结果，从而有助于理解为何Permalloy很软这个长期未解决的问题。

Similarly, the AMR begin to increase and then decrease with increasing the thickness d of the seed layer, and has a maximum value at a critical thickness d of 5.32nm. Compared to the permalloy films deposited on Ta seed layer ,the AMR enhancement of 10%-46% is observed in the permallay films deposited on (Ni0.82Fe0.18)1-xNbx seed layer.(2) The coercivity Hc1 obtained for magnetic field H applied paralley to the easyaxis is large than Hc2 for H applied perpendicular to the in-plane easy axis, and both of coercivity are consistent with the change of x.

2沿样品易轴方向的矫顽力Hc_1比难轴方向的矫顽力Hc_2大，两者随Nb原子的百分含量x的变化是一致的，饱和磁化强度Ms随x的增大先增大后减小，在x=27.1％处，Hc_1和Hc_2都比较小，而Ms则达到最大；种子层厚度d不能明显改变坡莫合金薄膜的磁性能；与以传统材料Ta为种子层的坡莫合金薄膜相比，以Ni_(0.82Fe_(0.18)_(0.829)Nb_(0.271)为种子层的坡莫合金薄膜的矫顽力只有轻微减小，但是Msg 以w讪Fq.t）lkNk为种于层的坡莫合全薄膜的各向异性戳电阻及磁性能研究却要大，mk坡莫合金层厂度！
