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)计划以及既定的激励竞争性研究计划(EPSCoR)支持。新墨西哥大学的马丁·柯克教授及其同事维克托·阿科斯塔、丹尼尔·费泽尔、弗朗西丝卡·卡瓦洛和阿卜杜勒加尼·拉拉维获得了一套磁性测量系统(MPMS)。该仪器也被称为磁力计，是一种非常灵敏的测量磁场的设备。它用于测量分子、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都很重要。例如，该仪器非常适合用于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的晶体管的性能。该仪器为新墨西哥州大学校园以外的新墨西哥州地区提供了资源。另有四所拉美裔服务机构的教职员工使用这种仪器(新墨西哥西部大学、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)。本科生和研究生正在接受这种最先进的乐器的培训。该奖项旨在加强各级的研究和教育。研究了具有磁性纳米颗粒的细胞结合生物标记物，以使其能够使用超灵敏的钻石磁性显微镜进行非侵入性检测。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动电阻的研究正在进行中。对激光、探测器和晶体管的III-V类材料进行了调查，并对顺磁传感器和超导电子学进行了磁学和输运研究。还进行了基于钻石中氮空位中心的磁测量对凝聚态物理现象的纳米级探测。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势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.
