ABSTRACT
This Major Research Instrumentation award will provide support for the acquisition of a state-of-the-art magnetometer that combines extreme sensitivity with multiple measurement modes. The instrument will meet a critical need for cutting-edge magnetic characterization, particularly for a wide variety of functional magnetic and superconducting nanostructures, on the Georgetown campus and in the greater District of Columbia area. The research projects that will be enabled by this instrument have potentially major technological impacts in low power nanoelectronics, quantum computation, magnetic recording, magnetic semiconductors, nanophotonics, catalysis and bioinorganic chemistry, magnetic resonance imaging, and hyperthermia therapeutics. The instrument will have a strong impact on broadening participation of underrepresented groups in STEM fields from a broad user base at Georgetown and nearby institutions. It will also be utilized to provide research experience for undergraduate students through several partner REU programs.
This Major Research Instrumentation award support the acquisition of a Magnetic Property Measurement System (MPMS3), with unique technical features that are critical to support many current and future research efforts at Georgetown University. The extreme sensitivity, wide magnetic field range and temperature span, versatile operation modes, and cryogen-free capability are essential for studying a wide variety of technologically important magnetic and superconducting materials. The interdisciplinary research projects that will be enabled by this instrument include topological spin textures, chiral Majorana fermions, next generation heat-assisted magnetic recording media, single-molecule magnets, magnetic semiconductors, biomedical applications of magnetic nanoparticles, structure-property relationships in f-element materials, paramagnetic molecular complexes in catalysis and bioinorganic chemistry, and molecular spintronics based computational and memory devices. The instrument will be integrated with graduate and undergraduate curriculum to provide students with hands-on learning experiences, and promote teaching, learning and training.
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.

PROJECT OUTCOMES REPORT

This Project Outcomes Report for the General Public is displayed verbatim as submitted by the Principal Investigator (PI) for this award. Any opinions, findings, and conclusions or recommendations expressed in this Report are those of the PI and do not necessarily reflect the views of the National Science Foundation; NSF has not approved or endorsed its content.
Acquisition and installation of a Magnetic Property Measurement System (MPMS3) system have been completed in this project. The instrument is a state-of-the-art magnetometer that combines the extreme sensitivity of a Superconducting QUantum Interference Device (SQUID) with multiple measurement modes. It meets a critical need for cutting-edge magnetic characterization, particularly for a wide variety of functional magnetic nanostructures, on the Georgetown campus and in the greater Washington, DC area.
Intellectual Merit
The MPMS3 instrument has unique technical features that are critical to support many NSF-funded projects as well as other research efforts: its extreme sensitivity allows measurement of magnetic nanoparticles, nanowires, and ultrathin films with the smallest dimensions; the wide magnetic field range and temperature span, versatile operation modes, and cryogen-free Evercool capability are essential for studying a wide variety of technologically important magnetic and superconducting materials.
A broad range of ground-breaking interdisciplinary research projects have been enabled by this instrument. For example, we have demonstrated that interlayer exchange coupling between a reference and a free magnet can be used to stabilize a whirling magnetic configuration known as skyrmions, at room temperature and without any magnetic field, which are promising for low dissipation information storage; we have probed magnetic interactions in thermoelectric composite materials with micron-sized as well as nanoscale magnetic inclusions, and illustrated how the microstructures correlate with improved power factor and mechanical properties for applications in sustainable energy conversion; we have demonstrated the mechanisms for a newly developed two-way magnetic resonance tuning (TMRET) imaging technique that has profound impacts in improving magnetic resonance imaging (MRI) sensitivity and early cancer detection; we have revealed microscopic mechanisms of ionic migrations across buried interfaces and how they can be employed to electrically manipulate the magnetic responses, leading to novel concepts of energy-efficient nanoelectronic devices; we have also illustrated how magnetic nanoparticles can be infiltrated into cell walls of Scots pine sapwood and add additional functionalities.
Broader Impacts
This shared MPMS3 system has had major impacts for the research infrastructure at Georgetown University. It has provided urgently needed capabilities for magnetic characterizations. There is also a broad and growing user base from nearby institutions. The research projects that have been enabled by this instrument have potentially major technological impacts in low dissipation nanoelectronics, magneto-ionics, sustainable energy conversion, next generation magnetic recording media, magnetic resonance imaging, and bio-based functional materials. The results have been broadly disseminated through peer-reviewed publications, including several in high-impact journals in the field, and through many invited and contributed talks at conferences and research institutions. This instrument has had a strong impact on broadening participation of underrepresented groups in STEM fields. The instrument has been integrated with graduate and undergraduate curriculum to provide students with hands-on learning experiences. It has also been utilized to provide research experience for undergraduate students through local REU programs.
