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.

该提案要求凯泽斯劳滕大学承担参与三国核对核联合国际研究与合作中心新概念自旋电子器件（简称：中心）的网络费用。这项合作包括来自日本仙台东北大学（由 Hideo Ohno 教授领导）、英国约克大学（由 Kevin OGrady 和 Atsufumi Hiroata 教授领导）以及凯泽斯劳滕磁学小组的团队。该中心的目标是加强现有的科学合作。该中心组织研讨会，并支持合作机构的初级和高级工作人员参观。初级职员将访问合作伙伴机构进行较长时间的访问（3至6个月），而高级职员将访问合作伙伴机构进行短期访问（1至2周）。通过这种方式，约克、仙台和凯泽斯劳滕之间在该中心的长期关系将得到显着扩展，并在核心到核心项目完成后持续下去。该资助计划是由日本科学振兴会发起的(JSPS) 与德国研究理事会 (DFG) 和英国工程与物理科学研究委员会 (EPSRC) 合作（参见 DFG 和 JSPS 之间的谅解备忘录，附件2）。日本方面，该中心已在竞争激烈的核心对核心计划中获得批准。 EPSRC 随后向英国合作伙伴提供了资助。对于凯泽斯劳滕申请人来说，研究资金可通过四项资助的研究计划获得（见附件 1）。这些项目涵盖了所有研究费用，但无法支付中心的额外网络和研讨会费用。所申请的资金将用于凯泽斯劳滕举办的两个研讨会，以及凯泽斯劳滕初级和高级工作人员参加交流计划的旅费。该中心的研究旨在提高 MRAM 的效率，并将其与自旋极化晶体管结合起来，在通用芯片上实现自旋电子存储器和逻辑。具体来说，该中心计划解决四个关键组成部分，即 MRAM、自旋晶体管、计算和新颖概念。高频磁特性发挥着重要作用，凯泽斯劳滕团队将专门解决这一问题。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极其重要，因此，遵循理想的策略，在芯片上的自旋电子存储逻辑方面取得更大的进展。与该中心的主要目标并行，凯泽斯劳滕小组将评估使用磁振子（自旋波的量子）作为信息载体进行信息处理的潜力。这有助于实现中心的总体目标：将基于电子的自旋电子学和 CMOS 技术连接起来。
