For Permalloy/FeMn bilayers, the exchange field and coercivity decay exponentially in time with the application of an applied field antiparallel to the unidirectional anisotropy direction.

通过Py／FeMn双层膜结构研究了反铁磁层的厚度对交换耦合热稳定的影响，发现对于Py／FeMn双层膜，在外场方向与单向各向异性方向反平行时，交换偏置场和矫顽力随时间的变化呈指数衰减，耦合场和矫顽力的相对变化随FeMn层的厚度衰减。

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.

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！
