This award supports Professor Guy Schupp, Dr. William Yelon and two graduate students of the University of Missouri to collaborate in research on glassy materials and ferroelectric phase transitions with Professor Walter Steiner and others of the Physics Department of the Technical University of Vienna. They are engaged in detailed investigations of the spin dynamics of cluster glasses above their freezing temperatures and the dynamics of the phase transition of lithium heptagermanate. These dynamical processes have been studied using high magnetic field, low temperature facilities in Vienna. Recently, the neutron and gamma ray scattering instruments at the Missouri University Research Reactor (MURR) have been significantly upgraded. This enables them to carry out expanded structural studies and examinations of dynamical and magnetic properties near phase transitions. The combination of complementary techniques made possible by the unique facilities at MURR and those in Vienna may provide new and fundamental insights into magnetic ordering and the dynamics of phase transitions in glassy and ferroelectric materials.

该奖项支持密苏里大学的 Guy Schupp 教授、William Yelon 博士和两名研究生与维也纳技术大学物理系的 Walter Steiner 教授和其他人合作研究玻璃材料和铁电相变。 他们正在详细研究团簇玻璃在冰点以上的自旋动力学以及七锗酸锂的相变动力学。 这些动力学过程已使用维也纳的高磁场、低温设施进行了研究。 最近，密苏里大学研究堆（MURR）的中子和伽马射线散射仪器得到了显着升级。 这使他们能够进行扩展的结构研究以及相变附近的动力学和磁性能的检查。 MURR 和维也纳的独特设施所实现的互补技术的结合可能为磁有序以及玻璃和铁电材料的相变动力学提供新的基本见解。
