NSF Nanosystems Engineering Research Center for Translational Applications ofNanoscaleMultiferroic Systems (T ANMS),Greg P. Carman,University of California Los Angeles (Lead), University of California Berkeley, CornellUniversity, California State University Northridge, and ETH Zurich Switzerland (Foreign)ABSTRACTTranslational Applications of Nanoscale Multiferroic Systems (TANMS) has three primary goals. The first goal is to transition the unique discoveries that the TANMS team has made on nanoscale multiferroic materials, i.e. control of magnetic spin structures with electric fields, into three applications: memory devices, miniaturized antenna systems, and nanoscale motors. The second goal is to uncover fundamentally new understandings of the physics governing the unique intrinsic coupling present in multiferroic materials at the nanoscale. This is accomplished through a combination of novel multi-scale modeling efforts and innovative multiferroic material development/testing processes. The third major goal is to develop an inclusive educational environment to guide the next generation of engineers through engineering research, project management, and entrepreneurial endeavors. The first two goals address a barrier that prevents further miniaturization of electronic devices. Eliminating this barrier has a significant impact on our society's reliance on conventional magnetic generation systems that are intrinsically energy inefficient in the small scale. TANMS premise is that electric field induced magnetic spin reorientation present in nanoscale multiferroics overcomes this efficiency problem and produces a wide range of miniaturization opportunities previously considered implausible. For the third goal, T ANMS focuses on transforming the engineering educational system by integrating students and teachers at all levels to promote diversity, participate in transitional research, and engender the notion that engineering and business careers are closely intertwined.Intellectual Merit: For the last several decades engineering has made significant progress toward miniaturizing electromagnetic devices, e.g. cell phones, computers, and wireless communication devices. However, the field is quickly reaching an impasse to further miniaturization mainly due to a reliance on inefficient electrical currents to produce and control magnetism in the small scale. TANMS seeks to establish a radically different approach relying on intrinsic magnetic property manipulation, i.e. magnetic spin reorientation, in a multiferroic. If properly designed, this magnetoelectric coupling is extremely large in the small scale where exchange coupling tightly binds adjacent atomic level spins creating single magnetic domains. The introduction of this new approach into applications for electromagnetic control provides a revolutionary advancement dramatically different from inefficient current based methods used in a wide range of electromagnetic devices including memory, antennas, and motors.Broader Impact: A major goal of the Center is to construct an environment which provides an educational pathway from cradle to career by relying on the unique I 0-year time horizon provided by an ERC. This is achieved through two synergistic programs, one during the academic school year and the other during the summer months, to introduce k-12 apd undergraduate students to engineering research and business opportunities throughout their educational career. Major consideration is also given to developing a heterogeneous workforce, representative of the national population, to overcome historical paradigms in engineering that limit diversity. T ANMS members strongly believe that students with diverse backgrounds have not been adequately educated regarding the benefits of being an engineer. While our society continues to glorify athletes and celebrities, the wealth of fulfilling opportunities available to engineers is not sufficiently articulated. TANMS strives to achieve this by establishing a new approach intertwining engineering research with business entrepreneurial endeavors.

NSF Nanosystems Engineering Research Center for Translational Applications of Nanoscale Multiferroic Systems（T ANMS），Greg P.卡曼，University of加州洛杉矶（Lead），University of加州Berkeley，Cornell University，加州州立大学Northridge，and ETH苏黎世Switzerland（Foreign）摘要Nanoscale Multiferroic Systems（TANMS）的转化应用有三个主要目标。第一个目标是将TANMS团队在纳米级多铁性材料上的独特发现，即用电场控制磁自旋结构，转化为三种应用：存储设备，小型化天线系统和纳米级电机。第二个目标是从根本上揭示新的理解的物理管理独特的内在耦合目前在多铁性材料在纳米尺度。这是通过新颖的多尺度建模工作和创新的多铁性材料开发/测试过程相结合来实现的。第三个主要目标是发展一个包容性的教育环境，通过工程研究，项目管理和创业努力指导下一代工程师。前两个目标解决了阻止电子设备进一步小型化的障碍。消除这一障碍对我们社会对传统磁发电系统的依赖有重大影响，传统磁发电系统在小规模上本质上是能源效率低下的。TANMS的前提是存在于纳米级多铁性材料中的电场诱导的磁自旋重取向克服了这种效率问题，并产生了广泛的小型化机会，以前认为这是不可能的。对于第三个目标，T ANMS的重点是通过整合各级学生和教师来改造工程教育系统，以促进多样性，参与过渡性研究，并产生工程和商业职业密切相关的概念。在过去的几十年里，工程学在电磁设备的电磁化方面取得了重大进展，例如手机，计算机，和无线通信设备。然而，该领域很快就陷入了进一步小型化的僵局，主要是由于依赖于低效的电流来产生和控制小规模的磁性。TANMS试图建立一种完全不同的方法，依赖于内在的磁性操纵，即磁自旋重取向，在多铁性。如果设计得当，这种磁电耦合在小尺度下是非常大的，其中交换耦合紧密地结合相邻的原子级自旋，从而产生单个磁畴。将这种新方法引入电磁控制应用提供了革命性的进步，与存储器、天线和电机等各种电磁设备中使用的低效电流方法截然不同。更广泛的影响：中心的一个主要目标是建立一个环境，提供从摇篮到职业生涯的教育途径，依靠独特的I 0-ERC提供的一年时间范围。这是通过两个协同计划，一个在学年和其他在夏季月份，介绍k-12的apd本科生工程研究和商业机会，在整个教育生涯中实现。主要考虑的是发展一个异质的劳动力，代表全国人口，克服工程的历史范式，限制多样性。T ANMS成员坚信，不同背景的学生没有得到足够的教育，成为一名工程师的好处。虽然我们的社会继续赞美运动员和名人，但工程师可以获得的丰富的实现机会并没有得到充分的阐述。TANMS努力通过建立一种新的方法来实现这一目标，将工程研究与商业创业努力交织在一起。
