EAPSI: Probing Phase Transitions in Magnetic Materials

这个项目探索材料磁性质的变化，这对我们理解超导体很重要。超导体是一种允许电流流动而没有电阻的材料。这些材料广泛用于核磁共振成像仪、磁悬浮列车和科学设备。更好的理解将带来更便宜、更实用的设备，以及新技术。在京都的样品种植专家吉村和吉教授的实验室工作，将使样品的快速生产和研究成为可能。本项目拟利用核磁共振技术研究具有二维电子结构的CsCo2Se2在反铁磁相变附近的自旋涨落。这将通过测量自旋晶格弛豫率（T1-1）作为温度的函数来实现。这种测量将在晶体中的每个核位点重复进行。该奖项隶属于东亚和太平洋暑期研究所项目，由美国国家科学基金会和日本科学促进会共同资助，支持一名美国研究生进行暑期研究。

This project explores changes in the magnetic properties of materials that are important to our understanding of superconductors. Superconductors are materials that allow the flow of electricity without electrical resistance. These materials are widely used in MRI machines, MagLev trains, and scientific equipment. A better understanding will lead to cheaper and more practical equipment, as well as new technologies. Working in the lab of the expert sample grower Professor Kazuyoshi Yoshimura in Kyoto will enable rapid sample production and study.This project proposes to use nuclear magnetic resonance (NMR) techniques to study spin fluctuations in CsCo2Se2, a material with a two dimensional electronic structure, near an antiferromagnetic phase transition. This will be done by measuring the spin lattice relaxation rate (T1-1 ) as a function of temperature. This measurement will be repeated at each nuclear site in the crystal. This award under the East Asia and Pacific Summer Institutes program supports summer research by a U.S. graduate student and is jointly funded by NSF and the Japan Society for the Promotion of Science.
