With this award, Florida State University (FSU) will establish a Magnetic Property Measurement System with versatile capabilities for accurate and precise measurements of magnetic properties of molecules and materials. The system will facilitate studies of magnetic behavior of matter at different length scales and under broadly variable conditions. The project will impact many areas, including inorganic and organic chemistry, condensed-matter physics, chemical physics, and materials science. This instrument is an integral part of teaching and research training of graduate and undergraduate students, who are involved in research on diverse topics related to fundamental understanding and practical applications of magnetism and magnetic materials. The resource will be also utilized by neighboring primarily-undergraduate and minority-serving institutions, as well as in practical hands-on exercises during the undergraduate summer school on magnetism and magnetic materials held biennially on the FSU campus. In particular, the project will leverage the proximity of the Florida Agricultural and Mechanical University (FAMU) to facilitate training of students from the joint FAMU-FSU College of Engineering.The versatility and reliability of the requested cryogen-free system will help establish a broad user base. The research directions pursued by the project team and other major users include magneto-structural phase transitions that underlie energy-conversion technologies, emergent properties of correlated magnetic materials, synthesis of new magnetic materials in molten metal fluxes, controlled modulation of magnetism by surface organic molecules, correlated magnetic/plasmonic properties of quantum dots, magnetic exchange interactions in metal-organic frameworks under high pressure, and spin-state switching in transition metal complexes with radical anions.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

凭借该奖项，佛罗里达州立大学 (FSU) 将建立一个具有多功能功能的磁特性测量系统，可准确测量分子和材料的磁特性。该系统将有助于研究不同长度尺度和广泛变化条件下物质的磁性行为。该项目将影响许多领域，包括无机和有机化学、凝聚态物理、化学物理和材料科学。该仪器是研究生和本科生教学和研究培训的一个组成部分，研究生和本科生参与与磁性和磁性材料的基本理解和实际应用相关的各种主题的研究。该资源还将被邻近的主要本科和少数族裔服务机构以及在佛罗里达州立大学校园每两年举办一次的磁性和磁性材料本科生暑期学校期间的实际操作练习所利用。特别是，该项目将利用佛罗里达农业机械大学 (FAMU) 的地理位置，促进 FAMU-FSU 联合工程学院学生的培训。所需的无冷冻剂系统的多功能性和可靠性将有助于建立广泛的应用领域。用户基础。项目团队和其他主要用户追求的研究方向包括作为能量转换技术基础的磁结构相变、相关磁性材料的涌现特性、熔融金属熔剂中新型磁性材料的合成、表面有机分子对磁性的控制调制、量子点的相关磁性/等离子体特性、高压下金属有机框架中的磁交换相互作用以及过渡金属配合物与自由基阴离子的自旋态转换。该奖项反映了 NSF 的法定使命，并通过评估被认为值得支持利用基金会的智力优势和更广泛的影响审查标准。
