摘要:

在这篇文章中,在一个单一的亚微米和多终端的铁磁结构的横向几何结构的磁化运动的详细表征是在GHz的制度,使用直接直流表征技术。我们证明了Stoner-Wohlfarth模型对大长径比磁性纳米结构的适用性。应用该模型的实验数据,我们能够提取相关的磁化运动参数,并显示高频感应电流和局部磁化之间的相关性。此外,直流电压产生的结构在谐振,与外部磁场下的形状各向异性轴的角度,是由该模型解释。

英文摘要:

In this article a detailed characterization of a magnetization motion in a single sub-micrometer and multi-terminal ferromagnetic structure in lateral geometry is performed in a GHz regime using direct DC characterization technique. We have shown applicability of the Stoner-Wohlfarth model to the magnetic nano-structure with large length to with ratio. Applying the model to experimental data we are able to extract relevant magnetization motion parameters and show a correlation between high frequency inductive currents and local magnetization. Additionally, DC voltage generated over the structure at the resonance, with external magnetic field under an angle to the shape anisotropy axis, is explained by the model.
