The objective of this collaborative research is to fabricate and study the magneto-electric interactions in novel one-dimensional ferromagnetic-ferroelectric nanostructures, and to exploit them for innovative device applications. The program is motivated by theoretical models that suggest much stronger interactions in such nanostructure geometries than in standard thin films and laminate structures. The approach is to synthesize nanowire and nanotube composites consisting of ferroelectric materials, such as lead zirconium titanante or barium titanate, with ferrimagnetic nickel- or cobalt ferrite. Intellectual Merit:A comprehensive research program is planned consisting of the following components: sample fabrication, structural characterization, magneto-electric interaction studies spanning a wide frequency range, device studies, and theoretical modeling. Efforts will focus on the creation of novel nanostructures using innovative processing methods and examine their use for a new class of microwave devices that are both electric and magnetic field tunable. At the University of Alabama, the PI will lead the sample fabrication, structural characterization and device fabrication efforts; while the physical property measurements, theoretical studies and device applications will be led by the PI at Oakland University.Broader Impact:The efforts will bring together a multidisciplinary team of investigators that will make significant contributions to scientific knowledge, education outreach and infrastructure, and potentially lead to a host of next-generation devices for the national defense and consumer electronics. The program will provide support for graduate and undergraduate students, including underrepresented minorities, and contribute to their broad interdisciplinary training. Project personnel will collaborate with local schools to facilitate participation by high school students in research.

这项协作研究的目的是在新型的一维铁磁 - 有线纳米结构中构建和研究磁电 - 电磁相互作用，并将它们用于创新设备应用。该程序是由理论模型激励的，这些模型表明，这种纳米结构几何形状的相互作用比标准薄膜和层压层结构中的相互作用要强得多。该方法是合成由铁电材料（例如二甲钛钛剂或泰坦盐）组成的纳米线和纳米管复合材料，以及铁磁性镍或钴铁素铁矿。智力优点：一项全面的研究计划，计划包括以下组成部分：样本制造，结构表征，磁性电动相互作用研究，涵盖了广泛的频率范围，设备研究和理论建模。努力将着重于使用创新处理方法创建新型纳米结构，并研究它们用于电气和磁场可调的新型微波设备的使用。在阿拉巴马大学，PI将领导样本制造，结构表征和装置制造工作；虽然Oakland University的PI将领导物理财产测量，理论研究和设备应用。Boader的影响：努力将汇集一个多学科的研究人员团队，这些团队将为科学知识，教育宣传和基础设施做出重大贡献，并有可能导致许多国防和消费者的下一代能源。 该计划将为包括代表性不足的少数民族在内的研究生和本科生提供支持，并为其广泛的跨学科培训做出贡献。项目人员将与当地学校合作，促进高中生研究的参与。
