The objective of this EArly-concept Grant for Exploratory Research (EAGER) award is to develop new manufacturing processes for the magnetic components used in modern electronic systems. The goal is improve the manufacturability, performance, and energy efficiency of power supplies and wireless communication devices, while simultaneously reducing their size and weight. A novel process developed through the work will be used to combine the properties of two different magnetic materials incorporating magnetic particles of one type of material inside of a second material. The result is a new hybrid magnetic material (i.e. a composite of two materials) that exhibits improved material properties compared to existing magnetic materials. In the long run, these new magnetic materials are aimed at enabling next-generation mobile electronics, communication systems, robotics, and medical devices. The project will strengthen an industry/university research partnership between the University of Florida (UF) and Electron Energy Corporation (EEC) and provide a pathway for commercial testing of the methods and materials developed in the work through exchange of technical information and personnel exchanges. In additon, education of UF graduate students on the project will be enriched through their participation in a summer internship at EEC. The project also aims to broaden participation and retention of female and minority students in STEM career fields.Magnetic components used in modern electronic systems require compromising tradeoffs in size, power, and efficiency due to the lack of magnetic materials that simultaneously exhibit high saturation and low loss at MHz to GHz frequencies. To overcome this bottleneck a novel electro-infiltration process is planned, wherein magnetic nanoparticles are consolidated onto a surface, and the inter-particle gaps are filled by an electroplated magnetic material. The result is a two-phase nanocomposite with potentially transformative magnetic properties, along with a disruptive manufacturing technology integrate these materials within a variety of electronic systems. From a scientific standpoint, the electro-infiltration process provides a unique platform to fabricate new nanocomposite architectures. This enables fundamental exploration of exchange-coupled or nanogranular soft magnetic cores, as well as hard (permanent) magnetic materials. The long-term impact of this work would be a scalable, end-to-end manufacturing process for compact magnetic device components with exceptional performance, low manufacturing cost, and integration with other electronic devices. The specific aims of this one-year EAGER project are to validate the feasibility of the process, while beginning to optimize micro/nanofabrication methods and elucidate structure/property/performance relationships for these new electro-infiltrated nanocomposite magnetic materials.

EARLY概念探索性研究奖（EAGER）的目的是为现代电子系统中使用的磁性元件开发新的制造工艺。目标是提高电源和无线通信设备的可制造性、性能和能效，同时减小其尺寸和重量。通过这项工作开发的一种新工艺将用于联合收割机，将两种不同的磁性材料的特性结合起来，在第二种材料中加入一种材料的磁性颗粒。 结果是一种新的混合磁性材料（即两种材料的复合物），与现有的磁性材料相比，其表现出改善的材料性能。 从长远来看，这些新的磁性材料旨在实现下一代移动的电子产品，通信系统，机器人和医疗设备。该项目将加强佛罗里达大学（UF）和电子能源公司（EEC）之间的工业/大学研究伙伴关系，并通过技术信息交流和人员交流为工作中开发的方法和材料的商业测试提供途径。此外，UF研究生对该项目的教育将通过他们在EEC的暑期实习参与丰富。该项目还旨在扩大女性和少数民族学生在STEM职业领域的参与和保留。由于缺乏在MHz至GHz频率下同时表现出高饱和度和低损耗的磁性材料，现代电子系统中使用的磁性元件需要在尺寸，功率和效率方面进行折衷。为了克服这一瓶颈，计划了一种新的电渗透工艺，其中磁性纳米颗粒被固结到表面上，并且颗粒间的间隙由电镀的磁性材料填充。其结果是一种具有潜在变革性磁性的两相纳米复合材料，沿着一种颠覆性的制造技术将这些材料集成到各种电子系统中。从科学的角度来看，电渗透过程提供了一个独特的平台来制造新的纳米复合结构。这使得交换耦合或纳米颗粒软磁芯以及硬（永磁）磁性材料的基础探索成为可能。这项工作的长期影响将是一个可扩展的，端到端的制造工艺，用于具有卓越性能，低制造成本和与其他电子设备集成的紧凑型磁性设备组件。这个为期一年的EAGER项目的具体目标是验证该工艺的可行性，同时开始优化微/纳米制造方法，并阐明这些新型电渗透纳米复合磁性材料的结构/性能/性能关系。
