MRI: Acquisition of a Magnetic Property Measurement System (MPMS) To Support Research and Education in the State of New Mexico

该奖项由主要研究仪器（MRI）、化学研究仪器（CRIF）计划以及刺激竞争性研究的既定计划（EPSCoR）支持。新墨西哥大学的Martin Kirk教授及其同事Victor Acosta， Daniel Feezell， Francesca Cavallo和Abdelghani Laraoui已经获得了一个磁性测量系统（MPMS）。这种仪器，也被称为磁力计，是一种非常灵敏的测量磁场的装置。它用于测量分子、分子基材料、固态材料和器件的磁性能。这些磁性在许多应用中都很重要。例如，该仪器非常适合于在晶体管中表征背景杂质应用。这将有助于提高更高功率和更高频率晶体管的性能。该仪器作为新墨西哥大学校园以外新墨西哥地区的资源。另外四所西班牙裔服务机构（西新墨西哥大学、新墨西哥理工大学、新墨西哥高地大学和新墨西哥州立大学）的教员也在使用该仪器。本科生和研究生接受这一最先进仪器的训练。该奖项旨在加强各级的研究和教育。研究进行了细胞结合的生物标志物与磁性纳米颗粒，使其检测无创使用超灵敏的金刚石磁显微镜。研究人员正在对宽带隙垂直功率晶体管、垂直腔面发射激光器和发光二极管中的杂质浓度和差分电阻进行量化。对用于激光器、探测器和晶体管的III-V组材料进行了研究，并对顺磁传感器和超导电子设备进行了磁性和输运研究。基于金刚石中氮空位中心的磁强计在纳米尺度上探测凝聚态物理现象。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。

This award is supported by the Major Research Instrumentation (MRI), the Chemistry Research Instrumentation (CRIF) Programs as well as the Established Program to Stimulate Competitive Research (EPSCoR). Professor Martin Kirk from University of New Mexico and colleagues Victor Acosta, Daniel Feezell, Francesca Cavallo and Abdelghani Laraoui have acquired a magnetic property measurement system (MPMS.) The instrument, also known as a magnetometer, is a very sensitive device to measure magnetic fields. It is used to measure the magnetic properties of molecules, molecule-based materials, solid state materials and devices. These magnetic properties are important in many applications. For example, the instrument is ideally suited for characterizing background impurity applications in transistors. This will help improve the performance of higher power and higher frequency transistors. The instrument serves as a resource for the New Mexico region beyond UNM's campus. Faculty at four additional Hispanic serving institutions use the instrument (Western New Mexico University, New Mexico Tech, New Mexico Highlands, and New Mexico State University). Undergraduate and graduate research students receive training on this state-of-the-art instrument. The award is aimed at enhancing research and education at all levels. Research is conducted of cell-bound biomarkers with magnetic nanoparticles to enable their detection non-invasively using ultrasensitive diamond magnetic microscopy. Studies are underway to quantify impurity concentrations and differential resistance in wide-band-gap vertical power transistors, vertical-cavity surface-emitting lasers, and light-emitting diodes. Investigations are conducted of Groups III-V materials for lasers, detectors, and transistors, and carrying out magnetic and transport studies for paramagnetic sensors and superconducting electronics. Nanoscale probing of condensed matter physics phenomena with magnetometry based on nitrogen-vacancy centers in diamond is also carried out.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.
