项目摘要

The main aim of the research is to explore the fundamental magnetic, transport and collective properties of 3D multilayer structures and arrays. Such structures consist of ferromagnetic multilayers (typically 1-10nm thickness, fabricated from transition metals and alloys with non-magnetic layers as spacers) structured into rings down to 150nm diameter or smaller. The new class of structures presents significant fabrication, characterisation and measurement challenges which go well beyond the expertise of a single group but which we address in this proposal by building on the previous successful collaboration on single layer (2D) rings between the Cambridge and MIT groups. This previous collaboration has produced numerous publications in prestigious journals such as Phys. Rev. Letts. and the exchange of research students and postdoctoral researchers between the two groups which have been very fruitful and we expect this to provide a very strong base for the new collaboration. Specifically, the MIT group bring materials deposition and device fabrication expertise and expertise in device applications in spintronics to the project while the Cambridge group bring expertise in magnetic and optical measurements and in the interpretation of magnetic switching and dynamics. Together this makes a very strong team well suited to this ambitious project. We also propose to have several students and the post doctoral researcher involved participate in exchanges between the two institutions both to facilitate the research programme and to provide a training opportunity in an international context. Our goal is to create a novel 3D architecture based on multilayer ring structures, both as single entities and as arrays, in order to assess the potential of such structures for device and memory applications.
该研究的主要目的是探索三维多层结构和阵列的基本磁性,输运和集体性质。这种结构由铁磁多层膜(通常1- 10 nm厚,由过渡金属和合金制成,非磁性层作为间隔物)组成,结构为直径低至150 nm或更小的环。这类新的结构提出了重大的制造,表征和测量的挑战,远远超出了一个单一的小组的专业知识,但我们在这个建议中解决的基础上,以前成功的合作单层(2D)环之间的剑桥和麻省理工学院的团体。之前的合作已经在著名的期刊上发表了许多文章,如Phys. Rev. Lancaster。以及两个研究小组交换研究生和博士后研究人员,成绩斐然,我们期望这能为新的合作奠下稳固的基础。具体来说,麻省理工学院的小组带来了材料沉积和设备制造的专业知识和自旋电子学设备应用的专业知识,而剑桥小组带来了磁性和光学测量以及磁开关和动力学解释的专业知识。这使得一个非常强大的团队非常适合这个雄心勃勃的项目。我们还建议让几名学生和博士后研究人员参加两个机构之间的交流,以促进研究方案,并提供国际范围内的培训机会。我们的目标是创建一个新的3D架构的基础上多层环结构,作为单一的实体和阵列,以评估这种结构的设备和存储器应用的潜力。
