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. ***

De Long A超导量子干涉装置（SQUID）磁力计将被收购并安装为肯塔基大学材料表征设施的一部分。所要求的系统配置以适应材料科学与工程、化学和固态物理的各种应用。SQUID磁力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，具有电荷密度波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能，以及用于催化的纳米级磁性颗粒。该项目的首席研究员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）。这种能力对高温超导体和磁涡耗散的研究越来越重要。SQUID制造商已同意在此努力中充分合作。这项研究的一个独特优势是软件开发将提供给一般社区。数据分析包将使大量当前的SQUID磁力计用户能够轻松地添加这一重要功能，而无需构建或购买整个系统。＊＊＊
