铁磁纳米线阵列磁滞回线和FMR线形的角Preisach分析

Angular Preisach analysis of Hysteresis loops and FMR lineshapes of ferromagnetic nanowire arrays

C. Tannous, A. Ghaddar, J. Gieraltowski

摘要:

利用Preisach分析方法研究了在不同磁场与铁磁性镍纳米线阵列共轴夹角下的磁滞回线。当扩展到铁磁共振(FMR)线型,从相应的磁滞回线提取相同的参数集,Preisach分析表明,为了解释实验结果,应该使用不同的分布的相互作用或双折射率。检查磁滞回线和FMR线宽与场角的行为,我们推断,角度依赖性可能会被利用在角度传感设备,可以与各向异性(AMR)或巨磁阻(GMR)的设备竞争。

英文摘要:

Preisach analysis is applied to the study of hysteresis loops measured for different angles between the applied magnetic field and the common axis of ferromagnetic Nickel nanowire arrays. When extended to Ferromagnetic Resonance (FMR) lineshapes, with same set of parameters extracted from the corresponding hysteresis loops, Preisach analysis shows that a different distribution of interactions or coercivities ought to be used in order to explain experimental results. Inspecting the behavior of hysteresis loops and FMR linewidth versus field angle, we infer that angular dependence might be exploited in angle sensing devices that could compete with Anisotropic (AMR) or Giant Magnetoresistive (GMR) based devices.
