Current distribution in metallic multilayers from resistance measurements

Ondřej Stejskal, André Thiaville, Jaroslav Hamrle, Shunsuke Fukami, Hideo Ohno

摘要:

研究了一般结构Ta/Pt/(CoNi)/Pt/Ta多层膜中的面内电流分布。生长其中每层的厚度系统地变化的大量样品,随后测量每个样品的薄层电阻。这些数据通过一系列日益精细的模型进行分析,从宏观工程方法到介观输运理论。不可忽略的变化的估计层之间的电流再分配。具有额外的结构数据的重要性被突出。

英文摘要:

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.
