| 摘 要： | 详细研究了用溅射法制备的Ｆｅ／Ｍｏ多层膜系统的结构，磁性及磁电阻效应。发现当保护Ｍｏ层厚度为０．８ｎｍ、Ｆｅ层厚度ｄＦｅ由２．２ｎ，减到０．４ｎｍ时，ＧＭＲ在ｄＦｅ〈１．４ｎｍ有一迅速增加，并在ｄＦｅ＝０．９ｎｍ时达极大值，然后下降，矫顽力显示出类似的行为。

| Abstract: | The structure, Magnetic properties and giant magnetoresistance( GMR ) of sputtering deposited Fe/Mo multilayered thin films(MLF) with Mo layer thickness of 0 8nm and Fe layer thickness ranging from 0 4 nm to 2.2 nm have been investigated systematically. It is found that with the decrease of Fe layer thicknesses, GMR increases rapidly at d Fe <1.4 nm and reaches a maximum at d Fe =0.9 nm and then decreases. Combined with magnetic anisotropy and structure analysis, it is suggested that with the decrease of Fe layer thickness, the continuous MLF will gradually become discontinuous, and then turn into a granular film. The larger GMR comes from this kind of structure variation, and it is closely related to the internally magnetic inhomogeneity of the material. |
