The Analytical and Surface Chemistry Program of the Division of Chemistry (CHE) and the Metals Program of the Division of Material Research (DMR) will support the Small Grant for Exploratory Research (SGER) award of Prof. Petra Reinke of the University of Virginia. Prof. Reinke and her students aim to form for the first time magnetic nanostructures on silicon surfaces. Theoretical predictions indicate that the shape, position and bonding of the Mn-nanostructures on the Si-surface determine the magnetic properties of the assembly. Prof. Reinke will observe the assembly of the Mn-nanostructure with atomic scale resolution in a scanning tunneling microscope, use this data to tailor the Mn-Si structure, characterize the magnetic properties of these structures and evaluate their suitability for incorporation into spintronics devices. The study aims to unravel the connection between the atomic scale structure and bonding and the resultant magnetic properties of a Mn-nanostructure. It may strongly impact the field of spintronics device development.

化学部（CHE）的分析和表面化学计划和材料研究部（DMR）的金属计划将支持弗吉尼亚大学Petra Reinke教授的探索性研究（SGER）奖。Reinke教授和她的学生的目标是首次在硅表面形成磁性纳米结构。理论预测表明，Mn纳米结构在Si表面的形状、位置和键合决定了组装体的磁性能。Reinke教授将在扫描隧道显微镜中以原子尺度分辨率观察Mn纳米结构的组装，使用这些数据来定制Mn-Si结构，表征这些结构的磁性，并评估它们是否适合纳入自旋电子器件。该研究旨在揭示Mn纳米结构的原子尺度结构和键合之间的联系以及由此产生的磁性。它可能会对自旋电子学器件的发展产生重大影响。
