论文摘要
研究了通用结构TA/PT/（CONI）/pt/ta的多层内的平面电流轮廓。一组样品，其中每一层的厚度系统地生长了，然后进行测量每个样品的板电阻。从宏观工程方法到介观传输理论，通过一系列越来越复杂的模型来分析数据。发现层之间电流的估计重新分配的不可忽略的变化。强调拥有其他结构数据的重要性。
The in-plane current profile within multilayers of generic structure Ta/Pt/(CoNi)/Pt/Ta is investigated. A large set of samples where the thickness of each layer is systematically varied was grown, followed by the measurement of the sheet resistance of each sample. The data are analyzed by a series of increasingly elaborate models, from a macroscopic engineering approach to mesoscopic transport theory. Non-negligible variations of the estimated repartition of current between the layers are found. The importance of having additional structural data is highlighted.
