MRI: Acquisition of a Versatile Magnetic Property Measurement System

根据这份合同，佛罗里达州立大学（FSU）将建立一个具有多功能的磁性测量系统，用于精确测量分子和材料的磁性。该系统将有助于在不同长度尺度和广泛可变条件下研究物质的磁性行为。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训练的一个组成部分，他们参与了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。这些资源还将被邻近的主要本科院校和少数民族服务机构利用，以及在FSU校园每两年举行一次的本科生磁性和磁性材料暑期学校的实际动手练习中使用。特别是，该项目将利用佛罗里达农业和机械大学（FAMU）的邻近性，促进FAMU- fsu联合工程学院的学生培训。所要求的无低温系统的多功能性和可靠性将有助于建立广泛的用户基础。项目组和其他主要用户追求的研究方向包括：能量转换技术基础上的磁结构相变、相关磁性材料的涌现特性、新型磁性材料在熔融金属通量中的合成、表面有机分子对磁性的可控调制、量子点的相关磁/等离子体特性、高压下金属-有机框架中的磁交换相互作用、以及带有自由基阴离子的过渡金属配合物的自旋态转换。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

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.
