This project focuses on the synthesis and crystal growth of new platinum group metal oxides belonging to several different structural families. The synthesis of new materials will be approached from several directions, including solid state reactions for powder synthesis and the use of high temperature solution reactions for crystal growth. Great strides have been made in the development of new preparative approaches for platinum metal group oxide phases. These new methods will be applied toward the synthesis of new chemical compositions and help explore the composition-property-space of these oxides. To accomplish these tasks, undergraduates, graduate students and postdoctoral researchers will be trained in cutting edge synthetic and characterization techniques, such as flux growth of crystals, magnetic measurements on oriented single crystals, and structure determinations of new compounds using state of the art equipment, including high-temperature high-pressure reaction vessels, SQUID magnetometers and CCD based single crystal diffractometers. %%%Many important physical properties that enable the functioning of new electronic devices, data storage materials, battery components and superconductors are found in oxide materials containing transition metal elements. This is a versatile group of chemical compounds that can be selectively modified to exhibit desirable physical properties that will lay the groundwork for new devices and applications of the future. Advanced methods are being developed for synthesizing oxides containing selected transition metal elements from the platinum group, either as powders or as single crystals, in order to determine the atomic structure of these materials, to investigate their electronic and magnetic properties, and to enable their utilization in a variety of applications. To accomplish these tasks, undergraduates, graduate students and postdoctoral researchers are being trained in cutting-edge techniques for synthesizing and characterizing these materials using state of the art instrumentation. The educational aspect of this research assures that highly trained men, women and underrepresented minorities can enter the workforce and meet industry's need for scientists.

该项目的重点是属于几个不同结构家族的新铂族金属氧化物的合成和晶体生长。新材料的合成将从几个方向进行，包括粉末合成的固态反应和晶体生长的高温溶液反应的使用。 铂族金属氧化物相的新制备方法的发展已经取得了很大的进展。 这些新方法将应用于合成新的化学组成，并有助于探索这些氧化物的组成-性质-空间。 为了完成这些任务，本科生，研究生和博士后研究人员将接受尖端合成和表征技术的培训，例如晶体的通量生长，定向单晶的磁性测量，以及使用最先进的设备确定新化合物的结构，包括高温高压反应容器，SQUID磁强计和基于CCD的单晶衍射仪。 在含有过渡金属元素的氧化物材料中发现了许多重要的物理性质，这些性质使新的电子设备、数据存储材料、电池组件和超导体能够发挥作用。 这是一组多功能的化合物，可以选择性地进行修饰，以显示出理想的物理特性，这将为未来的新设备和应用奠定基础。 正在开发用于合成含有选自铂族的过渡金属元素的氧化物的粉末或单晶的先进方法，以确定这些材料的原子结构，研究它们的电子和磁性，并使它们能够用于各种应用。 为了完成这些任务，本科生，研究生和博士后研究人员正在接受尖端技术的培训，以使用最先进的仪器来合成和表征这些材料。 这项研究的教育方面确保受过良好训练的男子、妇女和代表性不足的少数民族能够进入劳动力市场，满足工业界对科学家的需求。
