Nanometer Scale Magnetic Resonance Imaging of Electron and Nuclear Spins
Abstract
The goal of the proposed work is to develop new methodologies in force-detected magnetic resonance for high resolution imaging of nuclear and electron spins. Three dimensional non-destructive imaging of materials on the atomic scale could provide fundamental new insight in materials research and structural biology. One of the central aims of this work will be to apply dynamic nuclear polarization (DNP) to hyperpolarize the nuclear spins in the sample. Achieving a large nuclear spin polarization is expected to significantly enhance detection sensitivity, and permit nuclear spin imaging on the 1-nm lengthscale. To achieve large DNP enhancements, we will construct a silicon nanowire force microscope capable of operating down to 350 mK, with the ability to excite magnetic resonance of electron and nuclear spins at a field of 1.2 T. This capability will be used to image single electron spins in biological samples containing electron spin labels. In addition to imaging, the proposed work will also focus on developing spin control protocols for performing high-resolution spectroscopic studies of nanometer scale nuclear spin ensembles.
