MRI: Acquisition: Characterization of and I/O for Magnetic Logic Structures

该项目的目标是获得一种用于研究纳米磁计算系统的材料精确溅射的沉积工具，以及一台用于确定其磁性的振动样品磁强计。研究人员选择了一种能够以良好的控制沉积各种多层膜的溅射系统，该系统由三个独立的腔室组成，能够进行射频/直流共溅射和等离子体氧化。研究小组还将获得一台振动样品磁强计/交流梯度磁强计，能够为这些材料生成滞后曲线。智能价值--该设备将用于纳米磁逻辑的研究。巴黎圣母院小组开创了用于数字逻辑的磁性量子点细胞自动机，这种自动机具有非易失性、密度高、低功耗、耐辐射、可在室温下运行。这种新的沉积系统将允许开发最佳的磁性材料、基于磁隧道结的输入/输出结构和磁轭计时线。这项工作提供了将存储器和逻辑结合在一起的全磁信息处理系统的前景。更广泛的影响--该设备将推动纳米磁逻辑的进步，在纳米电子学的更大背景下，这正成为一个重要的话题。此外，这项研究具有超越磁逻辑的影响，因为对磁堆的研究与商业磁随机存取存储器技术相关。将提供本科生和研究生的实验室经验，参与者来自巴黎圣母院和其他地方。此外，这些工具将用于教师和学生的暑期体验。将特别关注少数民族工程方案和女工程师协会。

The objective of this project is the acquisition of a deposition tool for the precise sputtering of materials for the study of nanomagnetic computing systems, and a vibrating-sample magnetometer to determine their magnetic properties. The investigators have selected a sputtering system capable of depositing a variety of multilayers with excellent control, which comprises three separate chambers capable of RF/DC co-sputtering and plasma oxidation. The team of investigators will also acquire a vibrating-sample magnetometer/alternating-gradient magnetometer that is capable of generating hysteresis curves for these materials. Intellectual Merit - This equipment will be used for research on nanomagnetic logic. The Notre Dame group has pioneered magnetic quantum-dot cellular automata for digital logic, which are non-volatile, dense, low-power, radiation hard, and operate at room temperature. This new deposition system will allow the development of optimum magnetic materials, input/output structures based on magnetic tunnel junctions, and magnetically-yoked clocking wires. This work offers the promise of all-magnetic information-processing systems, which combine memory and logic. Broader Impacts - This equipment will enable advances in nanomagnetic logic, which is becoming an important topic within the larger context of nanoelectronics. Moreover, this research has implications beyond magnetic logic since the study of magnetic stacks is relevant to commercial magnetic random-access-memory technology. Laboratory experiences at both the undergraduate and graduate levels will be offered, with participants from both Notre Dame and elsewhere. Moreover, these tools will be used in summer experiences for teachers and their students. Special attention will be given to the Minority Engineering Program and the Society of Women Engineers.
