Improvements in Mechanical Detection of Magnetic Resonance
Abstract
This program intended to provide substantial improvements to conditions that affect imaging nanoscale structures with atomic resolution and chemical specificity by magnetic resonance force microscopy. This is a final report of an 18 months effort. During this period we the following activities: We increased the sensitivity of the cantilever displacement readout and therefore the force sensitivity achievable with mechanical detection. We implemented an approach to reduce the spin noise in MRFM by shifting to higher frequencies the higher order cantilever vibrational modes. We build a low temperature microscope that operates in vacuum at 4K in a field of up to 9Tesla and tested the system. Finally, we selected CaF2 as the first sample to test the feasibility of performing magnetic resonance force spectroscopy within the resonance slice, prepared samples and characterized the sample.
