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 KP F6 and (N H4) 2 S O4 were used for demonstration, where a typical experiment measured signals of ∼ 1014 spins from a ∼0.8 μm wide imaging slice. By studying the decay of the dipolar echo maximum it is demonstrated that spectral linewidths of 1.1 kHz collected from a 100 kHz wide frequency slice can be obtained, extending the coherence lifetime for both samples by an order of magnitude. © 2006 The American Physical Society.
