本计画主要研究金属间化合物重费米子超导体之合成与结构特性。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）之间的合作努力，将生产和表征高质量样品，并进行详细的磁性和传输测量。 本科生和研究生的培训将强调进行调查，从基本的样品制备一直到测量技术和数据解释。一个社区教育推广计划将涉及高中科学教师在PI的实验室工作在夏季。 这将使这些教师能够体验研究和科学方法的作用，对当地的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。该提案旨在探索晶体学与稀土金属间化合物的超导性和磁性等结构相关性质的系统研究之间的有益边界。 随着新材料的合成，表征和性能测量的结合，这项研究将创造超导性和磁性的相互作用的基本理解，允许定制设计的新材料有用的信息技术。 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/传输特性，因为他们在LSU科学界和国家实验室内合作，获得更广泛，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有关的新科学观点回到教室。

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.
