Spin dynamics in magnetic nanostructures

电子的自旋，而不是它的电荷，在电子学中创造了非凡的机会，被称为自旋电子学。这一领域的快速发展要求在理解纳米几何结构中的自旋相互作用方面取得进一步的进展。我使用分子束外延(MBE)来沉积超薄膜和超晶格。射频、穆斯堡尔谱、DC和PS时间和亚微米分辨磁光克尔效应成像、电子输运、电子显微镜技术和电子束光刻技术为我们研究磁性纳米结构提供了必要的工具。我们的研究涉及自旋动力学，重点是自旋流的研究。我们使用蠕动自旋泵浦来产生没有净电荷输运的自旋流。纳米多层膜结构适合于确定自旋电子器件中磁电极之间正常金属互连中自旋输运的主要参数。我将把我们的研究活动扩大到两个新的方向：

The spin of the electron rather than its charge has created remarkable opportunities in electronics, coined spintronics. The rapid progress in this field requires further advances in understanding of spin interactions in nanoscopic geometries. I use Molecular Beam Epitaxy (MBE) for the deposition of ultrathin films and superlattices. Radio frequency, Mossbauer spectroscopy, dc and ps temporal and sub micron resolved magneto-optical Kerr effect imaging, electron transport, electron microscope techniques, and electron beam lithography provide us with the necessary tools in the study of magnetic nanostructures. Our studies involve spin dynamics with emphasis on the study of spin currents. We use peristaltic spin pumping to generate spin currents that are accompanied by no net electric charge transport. Nano multilayer structures are suitable for determining the main parameters governing the spin transport in normal metal interconnects between the magnetic electrodes in spintronics devices. I am going to broaden our research activity towards two new directions:
