Acquisition of a SQUID Magnetometer System for the University of Kentucky Materials Characterization Facility

小行星9512589 将购置并安装一台超导量子干涉装置（SQUID）磁强计，作为肯塔基州大学材料表征设施的一部分。所需的系统经过配置，可适应材料科学与工程、化学和固态物理学领域的各种应用。SQUID磁强计的直接用户将利用它来研究各向异性超导体中的涡旋动力学、具有电荷密度或自旋密度波的低维导体的热力学、新型富勒烯基化合物和聚合物的合成和性质以及用于催化的纳米级磁性颗粒。该项目的主要研究者将开发新的公共领域软件，用于分析当前仪器所不具备的非线性磁化率数据（高次谐波）。这种能力对于高温超导体和磁涡旋耗散的研究越来越重要。SQUID制造商已同意在这一努力中充分合作。 这项研究的一个独特优势是软件开发，将提供给广大社区。数据分析包将使大量现有SQUID磁强计用户能够轻松添加这一重要功能，而无需构建或购买整个系统。 ***

9512589 De Long A Superconducting Quantum Interference Device (SQUID) magnetometer will be acquired and installed as part of the Materials Characterization Facility of the University of Kentucky. The requested system is configured to accommodate a variety of applications in materials science and engineering, chemistry, and solid state physics. Immediate users of the SQUID magnetometer will utilize it to investigate vortex dynamics in anisotropic superconductors, thermodynamics of low- dimensional conductors with charge-density or spin-density waves, synthesis and properties of novel fullerene-based compounds and polymers, and nanoscale magnetic particles for use in catalysis. The principal investigator in this project will develop novel, public domain software for the analysis of nonlinear susceptibility data (higher harmonics) which the current instrument does not have. This capability is increasingly important for the study of high temperature superconductors and of magnetic vortex dissipation. The SQUID manufacturer has agreed to cooperate fully in this endeavor. %%% A unique strength of this research is the software development which will be made available to the general community. The data analysis package will enable a large number of current SQUID magnetometer users to easily add this important capability without having to build or buy whole systems. ***
