This proposal asks for the networking costs for the the University of Kaiserslautern to participate in the tri-national Core-to-Core Joint International Research and Collaborative Center New Concept Spintronic Devices (in short: Center). This collaboration includes groups from the Tohoku University, Sendai, Japan (led by Prof. Hideo Ohno), University of York, Great Britain (led by Profs. Kevin OGrady and Atsufumi Hiroata), and the Kaiserslautern magnetism group. The Center aim is to strengthen existing scientific collaborations. The Center organizes workshops, and supports visits for junior and senior level staff members at the partner institutions. Junior staff members will visit the partner institutions for a longer stays (3 to 6 months) while senior staff members will visit the partners for short visits (1-2 weeks). In this way the long standing relationships between York, Sendai and Kaiserslautern in the Center will be expanded signficantly to endure far beyond the completion of this Core-to-Core project.The funding scheme has been initiated by the Japanese Society for the Promotion of Science (JSPS) in collaboration with the Deutsche Forschungsgemeinschaft (DFG) and the Engineering and Physical Sciences Research Council (EPSRC), UK (see Memorandum of Understanding between DFG and JSPS, Annex 2). On the Japanese side, the Center has been approved in the highly competitive core-to-core program. EPSRC followed with a grant for the British partner. For the Kaiserslautern applicants funding for research is available via four funded research initiatives (see Annex 1). These projects cover all research costs, however they are not able to cover the additional networking and workshop costs of the Center. The requested funding will be used for two workshops in Kaiserslautern, as well as the travel of Kaiserslautern junior and senior staff members in the exchange program. This Center research aims to improve the efficiency of MRAM and to combine it with a spin-polarized transistor for spintronic memory and logic on a common chip. Specifically, the Center plans to address four key components, which are MRAM, spin transistor, calculations, and novel concepts. High-frequency magnetic properties play an important role and will be addressed specifically by the Kaiserslautern team. All partners consider it extremely important to gain access to the expertise and facilities at the other partner institutes, and thus, following an ideal strategy to make enhanced progress towards a spintronic memory logic on a chip. In parallel to the Centers major aims the Kaiserslautern group will evaluate the potential of information processing using magnons, the quanta of spin waves, as information carriers. This contributes to the overarching Center objective of interfacing electron-based spintronics and CMOS technology.

该建议要求为Kaiserslautern大学提供网络成本，以参加三国核心与核心联合国际研究和协作中心新概念Spintronic设备（简而言之：中心）。这项合作包括来自日本仙台的Tohoku大学（由Hideo Ohno教授领导），约克大学，英国大学（由凯文·奥格雷迪（Kevin Ogrady）教授和阿特苏夫米·福托塔（Atsufumi Hiroata）领导）和凯瑟斯·拉特恩（Kaiserslautern）磁性小组。中心目的是加强现有的科学合作。该中心组织研讨会，并支持合作伙伴机构的初级和高级工作人员的访问。初级工作人员将访问合作伙伴机构以更长的住宿（3至6个月），而高级工作人员将访问合作伙伴（1-2周）。通过这种方式，中心的约克，仙台和凯瑟斯兰之间的长期关系将显着扩展，远远超出了这个核心对核心项目的完成。 DFG和JSP之间的理解备忘录，附件2）。在日本方面，该中心已在竞争激烈的核心核心计划中获得批准。 EPSRC紧随其后为英国合作伙伴提供了赠款。对于Kaiserslautern的研究，可以通过四项资助的研究计划获得研究（参见附件1）。这些项目涵盖了所有研究成本，但是它们无法支付该中心的额外网络和研讨会成本。要求的资金将用于Kaiserslautern的两个研讨会，以及Kaiserslautern Junior和高级工作人员的旅行。该中心研究旨在提高MRAM的效率，并将其与自旋极化晶体管结合使用，以在常见芯片上进行自旋记忆和逻辑。具体而言，该中心计划解决四个关键组件，即MRAM，旋转晶体管，计算和新颖概念。高频磁性特性起着重要作用，将由Kaiserslautern团队专门解决。所有合作伙伴都认为，获得其他合作伙伴机构的专业知识和设施非常重要，因此，遵循理想的策略，以增强芯片的旋转记忆逻辑的进步。与中心的同时，Kaiserslautern组将评估使用镁，自旋波的量子作为信息载体的信息处理的潜力。这有助于将基于电子的Spintronics和CMOS技术接触的总体中心目标。
