DURIP- Acquisition of Quantum Scanning Microscope for Nanoscale Imaging of Spin Textures in Emergent 2D Magnets
Abstract
This proposal is for the acquisition of a scanning NV magnetometer to expand the PI s research abilities and research projects at University of Maryland, which include an ongoing AFOSR-supported project. The instrument integrates the functions of scanning NV magnetometry, magnetic force microscopy and atomic force microscopy, which allows the PI to study the proposed research on 2D magnets and heterostructures. The unique strength of this instrument is its integrated platform of multiple measurement modes, which allows the simultaneous measurements of magnetic nanostructures, and atomic structures and morphologies. The new instrument can offer a one-to-one image correspondence between magnetism and local lattice structure-morphology to enable the unprecedented understanding and control of the local magnetism and topological features. The PI will employ this new instrument and combine it with the existing electrical and optical measurement tools in the PI s lab to study nanoscale spin textures in emergent 2D magnets and develop the versatile control of the spin textures in 2D magnets. This effort has close relevance to the priorities of DoD s fundamental research (e.g., new quantum states and new quantum phases of matter) and technological developments (e.g., efficient nanoelectronic and spintronic computing, integrated magnetoelectric units as electrical and magnetic field sensors, and non-volatile memories). Once successful, it will produce timely results and knowledge for the innovative developments of ultracompact devices to advance the defense-prioritized technologies, including low-energy-consumption fault-tolerant computation and ultrasensitive electric-magnetic field sensors for long-range precision fires, rapid detection of hostile arms, and modernizing soldiers lethality. The acquisition of the intended equipment and the enabled research projects can provide excellent educational platforms to train the next-generation workforce in quantum materials and quantum sensing.
