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.

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。 来自新墨西哥州大学的Martin Kirk教授及其同事维克托Acosta、丹尼尔Feezell、Francesca Cavallo和Abdelghani Laraoui获得了一个磁特性测量系统（MPMS）。 该仪器，也称为磁力计，是一种非常灵敏的测量磁场的设备。 用于测量分子、分子基材料、固态材料和器件的磁性。这些磁性在许多应用中是重要的。 例如，该仪器非常适合表征晶体管中的背景杂质应用。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UNM校园以外的新墨西哥州地区的资源。 另外四所西班牙裔服务机构的教师使用该仪器（西新墨西哥州大学，新墨西哥州技术，新墨西哥州高地和新墨西哥州州立大学）。 本科生和研究生研究生接受这种最先进的仪器的培训。该奖项旨在加强各级的研究和教育。 研究是进行细胞结合的生物标志物与磁性纳米粒子，使他们的检测非侵入性使用超灵敏的金刚石磁显微镜。 目前正在进行研究，以量化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微分电阻。对用于激光器、探测器和晶体管的III-V族材料进行了研究，并对顺磁传感器和超导电子学进行了磁性和传输研究。该奖项反映了NSF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。
