项目摘要

This exploratory research program is directed towards the identification, synthesis, and characterization of mixed-valent transition metal oxides with charge ordering which results in coupling between electrical and magnetic properties. In this project, the emphasis is on the discovery of new classes of compounds where charge ordering can lead to ferroelectricity and magnetic order. The materials discovered in the program will have major impact in magnetic storage and sensing systems that are needed in next generation high-speed computers. Both graduate and undergraduate students will participate in this program and will acquire education and training in cutting-edge research techniques used in the materials synthesis, crystal structure analysis and electrical characterization using state-of-the-art research tools. Students will report research progress locally as well as give presentations of finished work at scientific meetings at national and international levels. %%%One area of intense research in solid state chemistry is the discovery of new compounds that can simultaneously exhibit various properties leading to multifunctional miniature electronic devices. A striking example is the coexistence of ferromagnetism and ferroelectricity in a single material platform that will revolutionize high speed computer industry by enabling devices that can read and write data simultaneously and is the subject of this program. Our exploratory research focuses on the identification, synthesis, and characterization of new and known oxide based materials containing transition elements with an ordered arrangement of electronic charges giving rise to strong coupling between electrical and magnetic properties. This program provides training for both undergraduate and graduate students in synthetic materials chemistry, crystal structure analysis and electronic properties. It will also provide these students with the intellectual challenge of understanding the complex behavior of newly synthesized materials and help forge links between chemistry, physics and material science. Connections to high school students will be extended via presentations and by making available hands-on research experiences in PI laboratories. Students participating in this research program will have an experience that will prepare them well for the modern industrial environment.
这个探索性的研究计划是针对混合价过渡金属氧化物的识别,合成和表征与电荷有序,从而导致电和磁性能之间的耦合。在这个项目中,重点是发现新的化合物类别,其中电荷有序可以导致铁电性和磁序。该计划中发现的材料将对下一代高速计算机所需的磁存储和传感系统产生重大影响。研究生和本科生都将参加该计划,并将获得使用最先进的研究工具在材料合成,晶体结构分析和电气表征中使用的尖端研究技术的教育和培训。 学生将在当地报告研究进展,并在国家和国际层面的科学会议上介绍已完成的工作。 固态化学中的一个密集研究领域是发现可以同时表现出多种特性的新化合物,从而导致多功能微型电子器件。 一个突出的例子是铁磁性和铁电性在单一材料平台中的共存,这将通过使设备能够同时读取和写入数据来彻底改变高速计算机行业,这也是该计划的主题。 我们的探索性研究集中在新的和已知的氧化物基材料的识别,合成和表征,这些材料包含具有有序排列的电子电荷的过渡元素,从而产生电和磁性能之间的强耦合。该计划为本科生和研究生提供合成材料化学,晶体结构分析和电子性质的培训。它还将为这些学生提供理解新合成材料的复杂行为的智力挑战,并帮助建立化学,物理和材料科学之间的联系。与高中生的联系将通过演讲和在PI实验室提供实践研究经验来扩展。参加这项研究计划的学生将有一个经验,这将使他们为现代工业环境做好准备。
