0437293JilesThis three-year U.S.-U.K. cooperative research project between the research group led by David Jiles at Iowa State University and A. J. Moses of the Wolfson Centre for Magnetics and Technology at the University of Cardiff addresses investigations in the magnetic and magneto elastic properties of a new class of magneto elastic composite materials. The proposal adds an international dimension to an existing NSF grant in materials research. Intellectual Merit The investigators plan to conduct materials characterization measurements using state-of-the-art facilities at the Wolfson Centre. The investigators are focusing on hysteresis (loss of magnetism) - a problem common to composite magnetic materials. They will study the magneto mechanical properties in order to understand their function and to produce materials with the desired properties of low hysteresis loss and high stress sensitivity. Broader Impacts In addition to the scientific research proposed here, the project also has a strong educational and training component. Through the international dimension, U.S. graduate students and a postdoctoral research will have an opportunity to learn about magnetic materials characterization methods being developed at the University of Cardiff using their state-of-the-art facilities. They will have developed research experience with an international team. There are plans to integrate the research results into an instructional course on magnetic materials and to involve undergraduate researchers through Iowa State's NSF-sponsored Research for Undergraduates Site.

0437293吉尔斯这三年的美国-英国由州立大学爱荷华州的大卫吉尔斯领导的研究小组与A.卡迪夫大学沃尔夫森磁性与技术中心的J. Moses研究了一类新的磁弹性复合材料的磁性和磁弹性特性。 该提案为现有的NSF材料研究拨款增加了国际层面。研究人员计划使用欧胜中心最先进的设施进行材料特性测量。研究人员正在关注磁滞（磁性损失）-复合磁性材料的常见问题。 他们将研究磁机械性能，以了解它们的功能，并生产具有低磁滞损耗和高应力敏感性的所需性能的材料。除了这里提出的科学研究之外，该项目还具有强大的教育和培训组成部分。通过国际层面，美国研究生和博士后研究将有机会了解卡迪夫大学利用其最先进的设施开发的磁性材料表征方法。 他们将与国际团队一起开发研究经验。 有计划将研究结果整合到磁性材料的教学课程中，并通过爱荷华州的NSF赞助的本科生研究网站让本科生研究人员参与进来。
