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

该项目的目标是获得一个沉积工具，用于精确溅射材料，以研究纳米磁性计算系统，以及一个振动样品磁力计，以确定其磁性。研究人员选择了一种溅射系统，该系统能够以出色的控制沉积各种多层膜，该系统包括三个独立的腔室，能够进行RF/DC共溅射和等离子体氧化。调查小组还将获得一个振动样品磁强计/交变梯度磁强计，能够为这些材料生成磁滞曲线。智力优点-该设备将用于纳米磁逻辑的研究。Notre Dame集团率先开发了用于数字逻辑的磁量子点细胞自动机，这种自动机具有非易失性、密度高、低功耗、抗辐射性，并且在室温下运行。这种新的沉积系统将允许开发最佳的磁性材料，基于磁性隧道结的输入/输出结构，以及磁轭时钟线。 这项工作为全磁信息处理系统提供了希望，这种系统将联合收割机存储器和逻辑结合起来。更广泛的影响-该设备将使纳米磁逻辑的进步，这正在成为纳米电子学更大背景下的一个重要课题。 此外，这项研究的影响超出了磁逻辑，因为磁堆栈的研究是相关的商业磁性随机存取存储器技术。 将提供本科和研究生阶段的实验室经验，参加者来自圣母大学和其他地方。此外，这些工具将用于教师和学生的暑期体验。将特别注意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.
