摘要

摘要 本研究调查了自旋扭矩二极管(STD)效应在复合自旋阀柱中的影响,复合自旋阀柱由不同的磁层和非磁层组成,排列方式为 AF/F0/NM1/F1/NM2/F2。我们的研究深入探讨了这种磁性多层系统中 STD 效应的基本机制。通过利用复合自旋阀支柱作为动态平台,我们揭示了自旋电荷传输和磁场之间错综复杂的相互作用。我们的研究旨在了解不同的结构参数,从而揭示其运行能力,并在不同的运行条件下优化其功能。此外,我们的探索还包括量化检测灵敏度,仔细研究输出电压和应用输入功率之间的关系。在研究中,我们对 STD 系统中的电流、电阻和灵敏度等关键参数进行了分析。我们的研究结果展示了自旋二极管效应在低维磁性结构中的表现。这一发现表明,制造具有多种潜在应用的自旋二极管器件是可行的。

Exploring the Spin Torque Diode Effect in Low Dimensional Magnetic Multilayer Structure

This study investigates the impact of spin torque diode (STD) effect in a composite spin valve pillar, comprising distinct magnetic and non-magnetic layers arranged as AF/F0/NM1/F1/NM2/F2. Our investigation delves into the foundational mechanisms governing the STD effect within this magnetic multilayer system. Through the utilization of the composite spin valve pillar as a dynamic platform, we unravel the intricate interplay between spin-dependent charge transport and magnetic fields. Our inquiry is to understand diverse structural parameters, allowing us to unveil its operational capabilities and optimize its functionality across varied operating conditions. Furthermore, our exploration encompasses the quantification of detection sensitivity, scrutinizing the relationship between output voltage and applied input power. In our study, we have done an analysis of crucial parameters such as current, resistance, and sensitivity in the STD system. Our findings showcase the manifestation of the spin diode effect in low-dimensional magnetic structure. This finding indicates the feasibility of fabricating a spin diode device with diverse potential applications.
