“…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.…”

The ability to measure weak signals such as pressure, force, electric field, and temperature with nanoscale devices and high spatial resolution offers a wide range of applications in fundamental and applied sciences. Here we present a proposal for a hybrid device composed of thin film layers of diamond with color centers implanted and piezo-active elements for the transduction and measurement of a wide variety of physical signals. The magnetic response of a piezomagnetic layer to an external stress or a stress induced by the change of electric field and temperature is shown to affect significantly the spin properties of nitrogen-vacancy centers in diamond. Under ambient conditions, realistic environmental noise and material imperfections, our detailed numerical studies show that this hybrid device can achieve significant improvements in sensitivity over the pure diamond based approach in combination with nanometer scale spatial resolution. Beyond its applications in quantum sensing the proposed hybrid architecture offers novel possibilities for engineering strong coherent couplings between nanomechanical oscillator and solid state spin qubits.Introduction.-The sensitive measurement of signals, such as force, pressure, electric field, temperature, with high spatial resolution possesses a wide range of applications in physics, engineering and the life sciences. Conventional methods, e.g. for pressure detection can usually operate at length scales down to the micron scale. Going beyond this regime whilst retaining highest sensitivity represents a significant challenge.

“…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.…”

Nitrogen vacancy-centered diamond has recently emerged as a promising material for various applications due to its special optical and magnetic properties. In particular, its applications as a fluorescent biomarker with small toxicity, magnetic field and electric field sensors have been a topic of great interest. Recent review 1 (R. Schirhagl et al 2014) introduced those applications using single NV-center in nanodiamond. In this minireview, I introduce the rapidly emerging DNP (Dynamic Nuclear Polarization) field using optically-pumped NV center in diamonds. Additionally, the possibility of exploiting the optically-pumped NV center for polarization transfer source, which will produce a profound impact on room temperature DNP, will be discussed.

“…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].…”

Anticrossing Spin Dynamics of Diamond Nitrogen-Vacancy Centers and All-Optical Low-Frequency Magnetometry

We investigate the photo-induced spin dynamics of single nitrogen-vacancy (NV) centres in diamond near the electronic ground state level anti-crossing (GSLAC), which occurs at an axial magnetic field around 1024 G. Using optically detected magnetic resonance spectroscopy, we first find that the electron spin transition frequency can be tuned down to 100 kHz for the 14 NV centre, while for the 15 NV centre the transition strength vanishes for frequencies below about 2 MHz owing to the GSLAC level structure. Using optical pulses to prepare and readout the spin state, we observe coherent spin oscillations at 1024 G for the 14 NV, which originate from spin mixing induced by residual transverse magnetic fields. This effect is responsible for limiting the smallest observable transition frequency, which can span two orders of magnitude from 100 kHz to tens of MHz depending on the local magnetic noise. A similar feature is observed for the 15 NV centre at 1024 G. As an application of these findings, we demonstrate all-optical detection and spectroscopy of externally-generated fluctuating magnetic fields at frequencies from 8 MHz down to 500 kHz, using a 14 NV centre. Since the Larmor frequency of most nuclear spin species lies within this frequency range near the GSLAC, these results pave the way towards all-optical, nanoscale nuclear magnetic resonance spectroscopy, using longitudinal spin cross-relaxation.
