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.

本项目致力于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与稀土阳离子、主族、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)的合作努力，将生产和表征高质量的样品，并将进行详细的磁性和运输测量。本科生和研究生的培训将强调开展从基本样品制备到测量技术和数据解释的各种调查。社区教育外展计划将让高中科学教师在暑假期间在PI的实验室工作。这将让这些教师在实践中体验研究和科学方法，对当地的物理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学校的课堂上进行化学演示。这项建议旨在探索结晶学和系统研究稀土金属间化合物的超导和磁性等结构相关性质之间的有益界限。结合新材料的合成、表征和性能测量，这项研究将使人们对超导和磁性的相互作用有一个基本的了解，从而允许对信息技术有用的新材料进行量身定制的设计。学生们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/传输特性，通过在路易斯安那州立大学科学界和国家实验室的合作，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学校进行化学示范。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有关的新科学观点回到课堂。
