AbstractThis proposal was received in response to Nanoscale Science and Engineering initiative, NSF 03-043, category NIRT. This program will utilize nanolithographically-patterned arrays to direct the assembly of nanoscale magnetic building blocks into specific architectures. These ordered assemblies will be designed for applications in high frequency, magnetotransport, and mechanical devices. Micromagnetics modeling of individual and collective properties, along with feedback from property measurements, will allow for an active refinement of architectural designs. As scientists develop materials with smaller and smaller sizes, there is a need to be able to integrate these tiny elements into devices of technological significance. In this program, very small components (much smaller than a human hair) will be assembled into ordered arrays by placing them onto surfaces that have specific grooved patterns. The grooves will serve to capture the components (e.g. small metal wires) in specific orientations. These arrangements will then be of interest for potential applications in communication or magnetic devices such as those important to cellular phones and computer hard drives, respectively. Additionally, an outreach component will involve both high school teachers and undergraduates from underrepresented groups in a nanoscience summer research program.

本提案是对NSF 03-043 NIRT类纳米科学与工程倡议的响应。该计划将利用纳米光刻图案阵列将纳米级磁性构建块的组装引导到特定的架构中。这些有序的组件将设计用于高频、磁传输和机械设备。对个人和集体属性的微磁学建模，以及来自属性测量的反馈，将允许积极改进建筑设计。随着科学家开发尺寸越来越小的材料，需要能够将这些微小的元素集成到具有技术意义的设备中。在这个程序中，非常小的组件(比人的头发小得多)将通过将它们放置在具有特定凹槽图案的表面上而组装成有序阵列。凹槽将用于捕获特定方向上的部件(例如小金属线)。然后，这些布置将在通信或磁性设备中的潜在应用中引起兴趣，例如分别对蜂窝电话和计算机硬盘驱动器重要的那些。此外，一个外展部分将包括高中教师和来自代表性不足群体的本科生参加纳米科学暑期研究计划。
