铁磁纳米线阵列的温度相关各向异性和弹性效应

Temperature dependent anisotropy and elastic effects in ferromagnetic nanowire arrays

C. Tannous, A. Ghaddar, J. Gieraltowski

摘要:

依赖于温度的铁磁共振测量作为镍纳米线阵列的直径的函数,揭示了这些系统中的几个有趣的功能。随着直径从100 nm减小到15 nm,在50 nm处观察到由表面各向异性增加引起的过渡,易轴取向从平行于单个纳米线几何轴到垂直于单个纳米线几何轴。共振场$H_{res}$温度变化(液氦和室温之间)的分析揭示了潜在的强大的磁弹性效应,在记录和自旋电子学的潜在应用在小直径和大直径纳米线阵列。

英文摘要:

Temperature dependent Ferromagnetic Resonance measurements performed as a function of diameter on Nickel nanowire arrays reveal several interesting features in these systems. With diameter decrease from 100 nm to 15 nm, a transition induced by surface anisotropy increase is observed at 50 nm in easy axis orientation from parallel to perpendicular with respect to individual nanowire geometric axis. Analysis of resonance field $H_{res}$ temperature variation (between liquid Helium and room temperature) reveals underlying strong magneto-elastic effects in small and large diameter nanowire arrays with potential applications in recording and spintronics.
