Magnetic sensors are used in every aspect of our lives, including compasses and sensors in planes, cars, and cell phones; the development of magnetic materials for electric motors; and magnetometers for medical imaging, data storage, geomagnetic prospecting, space exploration, and basic research. In particular, spin-precession magnetometers based on measurements of the Zeeman splitting of spin energy levels have long been accepted as the "gold standard for determining dc magnetic field strength. Currently available spin-precession magnetometers are bulky, costly, slow, and operate over limited field ranges. They are typically employed as fixed points for calibrating other types of sensors like Hall probes, magnetoresistive sensors, or fluxgate magnetometers. With the development of microsystems packaging methods that combine diverse technologies, it is possible to remove many of these limitations and create spin-precession magnetometers that can bring absolute, traceable measurements of magnetic field to many more applications in both industry and research. We envision a set of spin-based sensors that would span a range of fields from 10 microtesla to 100 teslas and have the required accuracy, resolution, dynamic range, slew rate, drift, and cost to meet current and future industry needs. We are interested in proposals that take a microsystems approach to developing such magnetometers, including novel integration schemes combining these materials with rf (nuclear magnetic resonance), microwave (electron paramagnetic resonance), terahertz, or optical components. Also important is the development of gyromagnetic materials with narrow spin-resonance linewidths, a well-defined gyromagnetic constant, and the necessary spin density for good signal-to-noise ratio. Work will be done in collabloration with Mark Keller.
