A Magnetic Resonance Force Microscope
Abstract
Key technologies required to bring the instrument to market with sensitivity to a few thousand protons were demonstrated including a novel cryogenic coarse approach mechanism and the first-ever batch fabrication of attoNewton-sensitive "ultrafloppy" cantilevers with individual nanomagnets on the tips. A prototype digital-signal-processor (DSP) based cantilever controller suitable for use in an MRFM instrument was developed. It is a significant accomplishment to be able to employ a DSP in a scanned probe microscope measurement. We have determined that this technology is suitable for optimization and manufacture of a commercial microscope, with initial applications in thin-film materials analysis. Eventual broad commercial and military applications will benefit from this technology including: research of advanced materials, advanced semiconductor-device research (e.g. individual impurity and defect characterization, assaying spin injection in spintronics devices), single-molecule analytical chemistry, infectious disease research, biotechnology, nanoelectronics, and new solid-state physics research.
