技术摘要相关电子材料为发现和研究新的基本磁性、结构和电子现象和相提供了无数机会，但到目前为止，它们的科学和技术潜力很可能只实现了一小部分。中子和X射线散射实验在这项工作中发挥着宝贵的作用，因为它们提供了关于新的物质相和它们之间的转变的基本结构和磁性信息。PI和他的学生将通过从事晶体生长和散射研究来解决相关电子材料领域中一些最及时和最具智力挑战的物理问题，这些研究可能掌握解决低维量子反铁磁体和高温超导体中无序的作用等关键问题的关键，特别是电子掺杂和汞基空穴掺杂化合物。PI的材料研究计划将继续提供丰富的教育机会，培养下一代材料物理学家。PI的学生生长的晶体将继续使他们能够与许多专家合作，并使用互补的实验技术向他们学习。非技术放弃复杂材料为发现和研究新的基本磁性、结构和电子现象和相提供了无数机会，到目前为止，它们的科学和技术潜力很可能只实现了一小部分。中子和X射线散射实验在这项工作中发挥着宝贵的作用，因为它们提供了关于新的物质相和它们之间的转变的基本结构和磁性信息。PI和他的学生将通过从事晶体生长和散射研究来解决相关电子材料领域中一些最及时、最具智力挑战的物理问题，这些研究可能是解决低维量子磁性和高温超导领域关键问题的关键。国际和平研究所的基于材料的研究计划将继续提供丰富的教育机会，在散裂中子源(SNS)和先进光子源(APS)等美国设施培训下一代材料物理学家。PI的学生生长的晶体将继续使他们能够与许多专家合作，并使用互补的实验技术向他们学习。

Technical AbstractCorrelated-electron materials provide myriad opportunities to discover and study novel fundamental magnetic, structural, and electronic phenomena and phases, and it is likely that only a small fraction of their scientific and technological potential has been realized so far. Neutron and X-ray scattering experiments play invaluable roles in this endeavor, since they provide essential structural and magnetic information about new phases of matter and the transitions between them. The PI and his students will address some of the most timely and intellectually challenging physics issues in the field of correlated-electron materials by pursuing crystal growth and scattering studies that are likely to hold the key to resolving such pivotal questions as the role of disorder in low-dimensional quantum antiferromagnets and high-temperature superconductors, especially the electron-doped and Hg-based hole-doped compounds. The PI's materials-based research program will continue to provide rich educational opportunities to train the next generation of materials physicists. The crystals grown by the PI's students will continue to enable them to collaborate with, and learn from many experts using complementary experimental techniques.
