9701579 Xiao In this GOALI supported research program magnetic tunnel junctions (MTJ) will be prepared and studied with ultra-fast laser spectroscopy, near-field optics, and magneto- tunneling. The purpose is to study the fundamental and technological issues essential to the performance and competitiveness of the MTJ. The proposed work is closely linked to activities at IBM Research, Yorktown Heights. IBM will, where appropriate, pay for the support of students for work done at IBM Research. This activity is jointly supported by DMR and the OMA office of the MPS Directorate. %%% Magnetic tunnel junctions are devices which are actively pursued by industry as the new memory and sensor elements such as data storage reading heads and non-volatile magnetic random-access-memory (MRSM) cells. The scientific issues include gaining a more complete understanding of the magnetic behavior of these systems, especially while illuminated by light and the effect of reducing the device size. The GOALI supported work links expertise at the academic institution with activities at IBM Research, Yorktown Heights. IBM will, where appropriate, pay for the support of students for work done at IBM Research. This activity is jointly supported by DMR and the OMA office of the MPS Directorate. ***

在这个GOALI支持的研究项目中，将利用超快激光光谱、近场光学和磁隧穿技术制备和研究磁隧道结（MTJ）。目的是研究对MTJ的性能和竞争力至关重要的基础和技术问题。拟议的工作与位于约克镇高地的IBM研究所的活动密切相关。在适当的情况下，IBM将为学生在IBM研究院完成的工作提供支持。这一活动由DMR和MPS理事会的OMA办公室共同支持。磁隧道结是工业界积极追求的新型存储器和传感器元件，如数据存储读取头和非易失性磁随机存取存储器（MRSM）单元。科学问题包括更全面地了解这些系统的磁性行为，特别是在光照和减小设备尺寸的影响下。目标倡议支持的工作将学术机构的专业知识与约克敦高地IBM研究所的活动联系起来。在适当的情况下，IBM将为学生在IBM研究院完成的工作提供支持。这一活动由DMR和MPS理事会的OMA办公室共同支持。＊＊＊
