Nanoscale Spin Transfer Devices and Materials

这是一项纳米磁学合作，涉及来自纽约大学和IBM，约克敦高地，纽约的研究人员。目的是进一步理解和应用纳米自旋转移器件和材料。在微型磁性器件中，电流可以在磁性层之间传输自旋角动量，并产生磁反转和磁激励。这可能使具有大磁各向异性的纳米磁体中的快速和相干反转成为可能-否则反转将需要大的局部磁场。这对于增加磁信息存储密度是重要的。该项目将通过研究新的器件结构和材料来解决有关电流和磁化之间相互作用的性质的重要基本问题。一个重要的组成部分是一个新的批量制造的纳米模板基板方法的应用，使纳米级的横向尺寸（100纳米）的多层结构的快速原型。这项研究将与年轻科学家的培训相结合：参与这项合作的研究生和本科生将通过学术界和工业界之间的互动以及纽约大学和IBM之间的许多计划中的学生交流而获益。这项研究计划亦会邀请对英特尔科学研究有兴趣的中学生参与，由纽约大学及IBM公司的研究人员共同参与，目的是加深对纳米磁性器件及材料的理解及应用。磁性纳米结构被广泛应用于信息处理中最先进的应用技术。这是美国的一个重要行业，正在迅速增长，全球对数据处理和存储的需求不断增加。最近发现，在微型磁性装置中，直流电可以通过称为自旋转移的机制来切换磁化方向。这是一个令人兴奋的发展，可能使磁信息处理和存储的显着改善。关于电流和磁化之间相互作用的性质，本项目将通过研究新的器件结构和材料来解决许多重要和基本的问题。这项研究将与磁学研究这一前沿领域的年轻科学家的培训相结合。参与这项合作的研究生和本科生将通过学术界和工业界之间的互动以及纽约大学和IBM之间的许多计划中的交流而获益。高中生（对英特尔科学研究感兴趣）也将参与这项研究。

This is a nanomagnetism collaboration that involves researchers from New York University and IBM, Yorktown Heights, NY. The aim is to further understand and apply nanoscale spin-transfer devices and materials. In miniature magnetic devices an electrical current can transport spin angular momentum between magnetic layers and produce magnetic reversal as well as magnetic excitations. This may enable rapid and coherent reversal in nanomagnets with large magnetic anisotropy -- a reversal that would otherwise require large local magnetic fields. This is important to increasing magnetic information storage density. This project will address important fundamental questions about the nature of the interaction between the current and the magnetization through studies of new device structures and materials. An essential component is the application of a new batch-fabricated nanostencil-substrate methodology to enable the rapid prototyping of multilayer structures with nanometer scale lateral dimensions (100 nm). This research will be integrated with the training of young scientists: Graduate and undergraduate students involved in this collaboration will gain by interactions between academia and industry and through the many planned student exchanges between NYU and IBM. High school students (with interests in Intel Science Research) will also participate in this research.This project brings together researchers from New York University and IBM with the aim of furthering the understanding and application of nanometer scale magnetic devices and materials. Magnetic nanostructures are widely used in technology with the most advanced applications found in information processing. This is a significant industry in the United States that is growing rapidly, with ever-increasing worldwide demands for data processing and storage. It has recently been discovered that in miniature magnetic devices a direct electrical current can switch the direction of magnetization by a mechanism know as spin-transfer. This is an exciting development that may enable dramatic improvements in magnetic information processing and storage. There are many important and fundamental questions about the nature of the interaction between the current and magnetization that this project will address through the investigation of new device structures and materials. This research will be integrated with the training of young scientists in this forefront area of magnetism research. Graduate and undergraduate students involved in this collaboration will gain by interactions between academia and industry and through the many planned exchanges between NYU and IBM.
