美国国家科学基金会纳米多铁系统转化应用研究中心（TANMS），Greg P. Carman，加州大学洛杉矶分校（领导），加州大学伯克利分校，康奈尔大学，加州州立大学北岭分校和瑞士苏黎世联邦理工学院（国外）摘要纳米多铁系统转化应用研究中心（TANMS）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，转化为三个应用：存储设备，小型化天线系统和纳米级电机。第二个目标是在纳米尺度上揭示控制多铁性材料中独特的内在耦合的物理学的根本新理解。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/测试过程的结合来完成的。第三个主要目标是建立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来指导下一代工程师。前两个目标解决了阻碍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性发电系统的依赖具有重大影响，这些系统在小范围内本质上是能源效率低下的。TANMS的前提是，电场诱导的磁自旋重定向存在于纳米级多铁体中，克服了这个效率问题，并产生了以前认为不可能的广泛的小型化机会。对于第三个目标，tanms的重点是通过整合各级学生和教师来促进多样性，参与过渡研究，并产生工程和商业职业紧密交织在一起的概念，从而改变工程教育体系。智力优势：在过去的几十年里，工程在小型化电磁设备方面取得了重大进展，例如手机、电脑和无线通信设备。然而，该领域正在迅速陷入进一步小型化的僵局，主要原因是依赖于低效的电流来产生和控制小规模的磁性。TANMS寻求建立一种完全不同的方法，依靠内在的磁性操纵，即磁自旋重定向，在多铁性中。如果设计得当，这种磁电耦合在小尺度上是非常大的，交换耦合紧密地结合相邻的原子水平自旋，产生单一的磁畴。将这种新方法引入到电磁控制的应用中，提供了一种革命性的进步，与在包括存储器、天线和电机在内的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ERC提供的独特的0年时间范围。这是通过两个协同项目实现的，一个在学年，另一个在夏季，向k-12本科学生介绍工程研究和商业机会，贯穿他们的教育生涯。主要考虑因素还包括发展一支代表全国人口的异质劳动力队伍，以克服限制多样性的工程历史范式。美国工程师学会成员强烈认为，拥有不同背景的学生并没有得到充分的教育，了解成为一名工程师的好处。当我们的社会继续赞美运动员和名人时，工程师们所能获得的丰富的实现机会却没有得到充分的阐述。TANMS致力于通过建立一种将工程研究与商业创业努力相结合的新方法来实现这一目标。

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.
