We demonstrate a nanostructure layer made of NiFe (permalloy:Py) thin film conjugated MoS nano-flakes. Layers are made based on a single-step co-deposition of Py and MoS from a single solution where ionic Ni and Fe and MoS flakes co-exist. Synthesized thin films with MoS flakes show increasing coercivity and enhancement in magneto-optical Kerr effect. Ferromagnetic resonance linewidth as well as the damping parameter increaseed significantly compared to that of the Py layer due to the presence of MoS. Raman spectroscopy and elemental mapping is used to show the quality of MoS within the Py thin film. Our synthesis method promises new opportunities for electrochemical production of functional spintronic-based devices.
我们展示了一种由镍铁（坡莫合金：Py）薄膜与二硫化钼纳米薄片共轭而成的纳米结构层。这些层是基于从单一溶液中一步共沉积Py和二硫化钼制成的，在该溶液中离子态的镍、铁和二硫化钼薄片共存。含有二硫化钼薄片的合成薄膜显示出矫顽力增加以及磁光克尔效应增强。由于二硫化钼的存在，与Py层相比，铁磁共振线宽以及阻尼参数显著增加。拉曼光谱和元素映射用于展示Py薄膜中二硫化钼的质量。我们的合成方法为基于功能自旋电子器件的电化学生产带来了新机遇。
