Abstract

Results are presented from studying the magnetostatic and magnetoresonant properties of a thin-film bilayer Fe₃Al/Pt structure synthesized via molecular beam epitaxy. Magnetometry and ferromagnetic resonance data indicate the four-fold in-plane magnetocrystalline anisotropy of the Fe₃Al layer. The magnetic field dependence of the voltage induced by the inverse spin Hall effect is measured under conditions of spin pumping, and the quantitative characteristic of the spin-charge transformation in platinum (the spin Hall angle) is estimated as θ_SH = 0.030 ± 0.005.

Fe3Al/Pt 双层中的铁磁共振和自旋霍尔效应

摘要本文介绍了通过分子束外延合成的薄膜双层 Fe3Al/Pt 结构的磁静力和磁共振特性研究结果。磁力测量和铁磁共振数据表明，Fe3Al 层具有四倍面内磁晶各向异性。在自旋泵条件下，测量了反自旋霍尔效应诱导电压的磁场依赖性，并估算出铂中自旋电荷转换的定量特征（自旋霍尔角）为 θSH = 0.030 ± 0.005。
