Abstract
Limits for extending the coherence lifetime in force detected NMR spectroscopy are explored using time suspension pulse sequences based on the ``magic echo.'' Two micron-sized single crystals of $\mathrm{K}\mathrm{P}{\mathrm{F}}_{6}$ and ${(\mathrm{N}{\mathrm{H}}_{4})}_{2}\mathrm{S}{\mathrm{O}}_{4}$ were used for demonstration, where a typical experiment measured signals of $\ensuremath{\sim}{10}^{14}$ spins from a $\ensuremath{\sim}0.8\phantom{\rule{0.3em}{0ex}}\ensuremath{\mu}\mathrm{m}$ wide imaging slice. By studying the decay of the dipolar echo maximum it is demonstrated that spectral linewidths of $1.1\phantom{\rule{0.3em}{0ex}}\mathrm{kHz}$ collected from a $100\phantom{\rule{0.3em}{0ex}}\mathrm{kHz}$ wide frequency slice can be obtained, extending the coherence lifetime for both samples by an order of magnitude.
