Career: Crystal-Chemical Relationships of Correlated Electronic Materials

本项目主要研究金属间重费米子超导体的合成和结构表征。我们的目标是将磁性能与稀土阳离子、主基团、过渡金属和晶体化学关系联系起来。通过路易斯安那州立大学（LSU）、洛斯阿拉莫斯国家实验室（LANL）、国家标准与技术研究所（NIST）和橡树岭国家实验室（ORNL）的合作，将生产出高质量的样品并对其进行表征，并进行详细的磁性和输运测量。本科生和研究生的培训将强调开展调查，从基本的样品制备一直到测量技术和数据解释。一项社区教育拓展计划将包括暑假期间在PI实验室工作的高中科学教师。这将使这些教师体验研究和科学方法在行动中对当地物理科学教育产生非常积极的影响。此外，路易斯安那州立大学的学生将在K-12学校的教室里进行化学演示。这一建议旨在探索晶体学和系统研究稀土金属间化合物的结构相关性质（如超导性和磁性）之间的有益边界。结合新材料的合成、表征和性能测量，本研究将对超导性和磁性的相互作用有一个基本的了解，从而为信息技术量身定制有用的新材料。学生将在路易斯安那州立大学（LSU）测量多晶和单晶材料的磁性和电子/输运特性，因为他们在LSU科学界和国家实验室合作，获得更广泛和更多样化的科学背景。路易斯安那州立大学的学生还将在东巴吞鲁日K-12学校进行化学演示。此外，一名高中教师将在小组中进行研究，并在学年期间带着与信息技术新材料相关的新的科学观点回到课堂。

This project is focused on the synthesis and structural characterization of intermetallic heavy fermion superconductors. It is our goal to correlate magnetic properties with rare earth cations, main group, transition metals, and crystal chemical relationships. Through cooperative efforts between Louisiana State University (LSU), Los Alamos National Laboratory (LANL), the National Institute of Standards and Technology (NIST), and Oak Ridge National Laboratory (ORNL), high quality samples will be produced and characterized, and detailed magnetic and transport measurements will be made. The training of undergraduate and graduate students will emphasize carrying out investigations ranging from basic sample preparation all the way through to measurement techniques and data interpretation. A community education outreach program will involve high-school science teachers working in the PI's lab during the summer. This will allow these teachers to experience research and the scientific method in action making a very positive impact on local physical science education. In addition, LSU students will perform chemistry demonstrations in K-12 school classrooms.This proposal is aimed at the exploration of the rewarding boundary between crystallography and the systematic study of structure-dependent properties such as superconductivity and magnetism in rare earth intermetallics. With the combination of synthesis, characterization, and measurements of properties of new materials, this research will create a basic understanding of the interplay of superconductivity and magnetism allowing the tailored design of new materials useful for information technology. Students will measure magnetic and electronic/ transport properties of polycrystalline and single crystal materials at Louisiana State University (LSU) gaining a broader and more diverse scientific background as they collaborate within the LSU scientific community and national laboratories. LSU students will also perform chemistry demonstrations in East Baton Rouge K-12 schools. In addition, a high school teacher will perform research in the group and return to the classroom during the academic year with new scientific perspectives, as related to new materials for information technology.
