The structural and magnetic properties of the evaporated Fe/V multilayers with a fixed V-layer thickness (tV = 1.5 nm) and variable Fe layer thicknesses (0.75 nm < or = tFe < or = 6 nm) have been studied by X-ray reflectivity and high-angle X-ray diffraction, conversion-electron Mössbauer spectrometry, and vibrating sample magnetometry. The results show that multilayers are formed with a broad Fe/V interface and pure crystalline bcc-Fe layers in the center of the individual subsystems. The Fe spin orientation is aligned in the film plane in the individual centers as well in the interfacial regions. The interfacial anisotropy constant Ks was estimated to be equal to 0.04 mJ/m2. This parallel magnetic anisotropy is discussed in terms of reduced symmetry effects on the hybridized 3d states.
通过X射线反射率和高角度X射线衍射、转换电子穆斯堡尔谱以及振动样品磁强计,研究了具有固定V层厚度(tV = 1.5 nm)和可变Fe层厚度(0.75 nm≤tFe≤6 nm)的蒸发Fe/V多层膜的结构和磁性。结果表明,多层膜形成了具有宽Fe/V界面的结构,且在各个子系统的中心有纯晶体体心立方-Fe层。Fe自旋取向在各个中心以及界面区域内与膜平面平行排列。界面各向异性常数Ks估计等于0.04 mJ/m2。这种平行磁各向异性是根据对杂化3d态对称性降低的影响来讨论的。
