中文摘要
在这项主要研究仪器计划(MRI)提案中,德克萨斯大学泛美分校(UTPA)正在申请资金以获得高磁场磁铁系统。该系统的获得将促进对新型分子材料的理解,并改善UTPA西班牙裔学生的教育机会。分子材料在世界范围内引起了强烈的兴趣,引发了磁学和输运研究领域的复兴。这些系统被许多人认为是未来的材料,因为它们具有广泛的特性,并且相对容易定制这些能力。这项工作的智力价值包括理解了三种分子导体中潜在的晶体结构与观察到的电子和磁性的关系,具有潜在的器件构建和基础科学的发展。这项工作将在整合和训练学生的同时,将UTPA材料科学的各个方面整合在一起。该项目的更广泛影响包括:1.)加强UTPA和其他没有这种能力的机构的科学家和工程师之间的合作;2.)促进对材料科学感兴趣的西班牙裔学生的研究生和本科教育;3.)在以西班牙裔为主的机构中,为科学家和工程师的教学制定教学策略。高磁场系统将允许长期使用,其自动化软件允许学生相对容易地集成。在这项主要研究仪器计划(MRI)提案中,德克萨斯大学泛美分校(UTPA)正在申请资金,以获得具有蒸汽氦回收能力和SQUID插入的17特斯拉超导磁体系统。许多高场技术,包括扭矩和SQUID磁强计,AMRO,量子振荡现象,如De Haas-van Alphen和Shubnikov-de Haas效应,将使用所要求的磁铁系统来系统地探测电输运和磁性(包括压力和温度依赖性)。我们将研究三类分子系统;这包括有机电荷转移盐(CTS)、低维分子磁体(MM)和纳米多孔金属有机框架(mof)。两种系统,CTS和mof目前正在UTPA生产,而MM系统正在东华盛顿大学合成。这一建议提供了必要的基础设施,以研究潜在的晶体结构关系,观察分子系统中的电子和磁性。该系统的获得将促进对新型分子材料的磁性和输运行为的理解,并显著改善UTPA西班牙裔学生的教育和培训机会。
英文摘要
In this Major Research Instrumentation Program (MRI) proposal, the University of Texas-Pan American (UTPA) is requesting funding to acquire a high field magnet system. Acquisition of this system will advance the understanding of novel molecular materials and improve educational opportunities for Hispanic students at UTPA. Molecular materials are of intense worldwide interest, initiating a renaissance in the field of magnetism and transport studies. These systems have been considered by many to be the materials of the future due to their wide range of properties and the relative ease to tailor those abilities. The intellectual merit of this work includes understanding the underlying crystal structural relationship to observed electronic and magnetic properties in three classes of molecular conductors with potential for device construction and development of basic science. This work will collectively merge aspects of material science at UTPA while integrating and training students. The broader impact of this project includes: 1.) enhanced cooperation between scientists and engineers at UTPA and other institutions without such capabilities 2.) promotion of graduate and undergraduate education of Hispanic students interested in material science, and 3.) the development of instructional strategies for scientists and engineers teaching in a predominantly Hispanic institution. The high magnetic field system will allow for long-term usage beyond the lifetime of the grant and its automated software allows for relative ease of student integration.In this Major Research Instrumentation Program (MRI) proposal, the University of Texas-Pan American (UTPA) is requesting funding to acquire a 17 Tesla superconducting magnet system with vapor helium recovery capabilities and a SQUID insert. A number of high field techniques, including torque and SQUID magnetometry, AMRO, quantum oscillatory phenomena such as De Haas-van Alphen and Shubnikov-de Haas effects, will be employed using the requested magnet system to systematically probe the electrical transport and magnetic properties (including pressure and temperature dependence). Three classes of molecular systems will be investigated; this includes organic charge transfer salts (CTS), low dimensional molecular magnets (MM), and nanoporous metal-organic frameworks (MOFs). Two systems, CTS and MOFs are currently being produced at UTPA, whereas the MM systems are being synthesized at Eastern Washington University. This proposal provides the infrastructure necessary to investigate the underlying crystal structural relationship to observed electronic and magnetic properties in molecular systems. Acquisition of this system will allow for the advancement of the understanding of magnetic and transport behavior in novel molecular materials and significant improves the educational and training opportunities for Hispanic students at UTPA.
