在MgO（001）衬底上，采用溅射沉积方法，以Fe和Pt作为双层籽晶层，生长了（001）Co 90 Fe 10/Cu多层膜。通过X射线衍射研究了Fe层厚度对Co_（90）Fe_（10）/Cu多层膜结构的影响，并与其对巨磁电阻效应的影响进行了比较。的结构质量，特别是最接近的种子双层的Co 90 Fe 10/Cu层，和磁阻的变化敏感地依赖于Fe种子层的厚度。最大的巨磁电阻效应被发现为铁厚度约12埃。Fe层厚度的影响进行了讨论，在衬底，Fe，Pt，和Co 90 Fe 10/Cu层之间的晶格匹配，和Fe和Pt在种子层中的合金化。(C)1998年美国物理学会。
Epitaxial (001) Co90Fe10/Cu multilayers were grown by sputter deposition on MgO(001) substrates using bilayer seed layers containing thin Fe and Pt layers. The influence of the thickness of the Fe layer on the structure of the Co90Fe10/Cu multilayers was studied by x-ray diffraction, and compared to its effect on the giant magnetoresistance measured in these films. The structural quality, especially of the Co90Fe10/Cu layers closest to the seed bilayer, and the change in magnetoresistance depend sensitively on the Fe seed layer thickness. The largest giant magnetoresistance effect is found for Fe thicknesses around 12 Angstrom. The influence of the Fe layer thickness is discussed in terms of lattice matching between the substrate, Fe, Pt, and Co90Fe10/Cu layers, and alloying of Fe and Pt in the seed layer.
