Nuclear magnetic resonance spectroscopy with single spin sensitivity

Abstract: Nuclear magnetic resonance spectroscopy and magnetic resonance imaging at the ultimate sensitivity limit of single molecules or single nuclear spins requires fundamentally new detection strategies. The strong coupling regime, when interaction between sensor and sample spins dominates all other interactions, is one such strategy. In this regime, classically forbidden detection of completely unpolarized nuclei is allowed, going beyond statistical fluctuations in magnetization. Here we realize strong coupling bet… Show more

“…The high spatial resolution is achieved thanks to the atomic size of the NV center and the ability for positioning it with high accuracy [5,[9][10][11][12][18][19][20] in nanoscale diamond. Besides its application in signal transduction and precision measurement, the proposed hybrid system can be exploited to couple the NV-center spin to mechanical oscillations, and significantly enhance the coherent coupling between these two degrees of freedom.…”

“…The growth of ultrapure isotopically modified diamond and subsequent nitrogen implantation make it possible to engineer NV centers close to the diamond surface [9][10][11][12] and therefore in close proximity to the piezomagnetic material layer. This allows for the detection of changes in the stray magnetic field [3,[13][14][15][16][17] generated by the piezomagnetic material due to an external stress.…”

“…While extensive researches have been focused on developing ways of shortening the length of NV center depth from diamond surface, it has been shortened only as much as 2 nm so far. 34 That distance induces a less than several kHz of hyperfine interaction. Therefore, we need to shorten the distance.…”

“…To obtain spectral information on the target spins, most studies so far have focussed on using T 2 -based techniques, which have been applied to the spectroscopy of small ensembles of either electronic [20][21][22][23] or nuclear spins [24][25][26][27][28]. However, spectroscopy can * jtetienne@unimelb.edu.au also be achieved by relying on T 1 processes, via crossrelaxation between a probe spin (the NV centre's electron spin) and the target spins [29][30][31][32][33].…”
