Abstract

The operation of a spin-injection emitter of electromagnetic oscillations with a Ni/NiO/Fe magnetic tunnel junction was first investigated. Using a nonconducting NiO spacer in a magnetic junction, the effect of the potential difference at the interface between magnetic layers on the efficiency of spin-injection emitters is determined. A model of the investigated emitter is theoretically described and the efficiencies of the emitters with a magnetic tunnel junction and a magnetic junction without an Ni/Fe spacer are experimentally compared. The possibility of enhancing the efficiency of the spin-injection emitter by using the magnetic tunnel junction is demonstrated.

NiO间隔物在隧道磁结中自旋注入下的电磁辐射

摘要

首先研究了具有Ni / NiO / Fe磁性隧道结的电磁振荡的自旋注入发射器的工作情况。在磁性结中使用不导电的NiO隔离层，可以确定磁性层之间界面处的电势差对自旋注入发射器效率的影响。理论上描述了所研究的发射器的模型，并通过实验比较了具有磁性隧道结和不具有Ni / Fe隔离层的磁性结的发射器的效率。证明了通过使用磁性隧道结来提高自旋注入发射器的效率的可能性。
