“…As shown in Fig. 2b, the mean ZFS parameter D increases linearly with the pressure with the coe cient of 0.31 ± 0.01 MHz/GPa, which is much less than the 14.6 MHz/GPa of the NV centers in diamond 6,10,11 . The smaller slope is bene cial for directly observing the shift of the ODMR signal with a large pressure range.…”

“…One of the great challenges of superconducting studies at high pressure is the measurement of magnetic properties and their evolution. However, conventional methods such as using superconducting quantum interference devices (SQUID) or the AC susceptibility cannot directly detect weak magnetic signals at microscale inside the diamond anvil cell (DAC) sample chamber [5][6][7][8][9][10][11] . Therefore, it is urgent to explore new methods for the magnetic detection.…”

Pressure is a significant parameter to investigate the properties of matter. The phenomenon of pressure-induced magnetic phase transition has attracted great interest due to its ability to detect superconducting behaviour at high pressures in diamond anvil cell. However, detection of the local sample magnetic properties is a great challenge due to the small sample chamber volume. Recently, in situ pressure-induced phase transition has been detected using optically detected magnetic resonance (ODMR) method of the nitrogen vacancies (NV) centers in diamond. However, the NV centers with four orientation axes and temperature-dependent zero-field-splitting present some difficulty to interpret the observed ODMR spectra. Here, we investigate and characterize the optical and spin properties of the implanted silicon vacancy defects in 4H-SiC, which is single-axis and temperature-independent zero-field-splitting. Using this technique, we observe the magnetic phase transition of a magnetic Nd2Fe14B sample at about 7 GPa. Finally, the critical temperature-pressure phase diagram of the superconductor YBa2Cu3O6.66 is mapped and refined. These experiments pave the way for the silicon vacancy-based quantum sensor being used in situ magnetic detection at high pressures.

Single qubit in solid-state materials recently emerges as a versatile platform for quantum information. Among them, the nitrogen vacancy (Nv) centre in diamond has become a powerful tool in quantum sensing for detecting various physics parameters, including electric and magnetic fields, temperature, force, strain, with ultimate precision and resolutions. it has been widely used in different conditions, from samples in ambient to samples in ultra-high pressure and low temperature. it can detect quantum phase transitions as well as neuron activities. Here we give a general review on both the physics of the sensing mechanism and protocols and applications.

“…1a.) Previous diamond strain measurements using NV centers [1,20,21,29,30] were performed via continuous wave optically detected magnetic resonance (CW-ODMR) -a simple, robust technique where laser and MW fields are continuously applied to the diamond and the MW frequency is swept or modulated. When the MW drive is resonant with the |0 → |±1 spin transitions, the output NV fluorescence decreases as population transfers between spin states.…”

“…Strain-mediated couplings also underlie hybrid quantum-nanomechanical systems [27,28]. Small diamonds as in situ strain sensors can be widely deployed as in high-pressure diamond anvil cells or in curing amorphous solids [29,30]. Finally, sensitive measurements of damage-induced strain in diamond are essential to proposed diamond-based particle detectors, such as for directional detection of dark matter consisting of weakly interacting massive particles (WIMPs) [31,32].…”

Crystal strain variation imposes significant limitations on many quantum sensing and information applications for solid-state defect qubits in diamond. Thus, precision measurement and control of diamond crystal strain is a key challenge. Here, we report diamond strain measurements with a unique set of capabilities, including micron-scale spatial resolution, millimeter-scale field-of-view, and a two order-of-magnitude improvement in volume-normalized sensitivity over previous work [1], reaching 5(2) × 10 −8 / Hz • µm 3 (with spin-strain coupling coefficients representing the dominant systematic uncertainty). We use strain-sensitive spin-state interferometry on ensembles of nitrogen vacancy (NV) color centers in single-crystal CVD bulk diamond with low strain gradients. This quantum interferometry technique provides insensitivity to magnetic-field inhomogeneity from the electronic and nuclear spin bath, thereby enabling long NV ensemble electronic spin dephasing times and enhanced strain sensitivity. We demonstrate the strain-sensitive measurement protocol first on a scanning confocal laser microscope, providing quantitative measurement of sensitivity as well as three-dimensional strain mapping; and second on a wide-field imaging quantum diamond microscope (QDM). Our strain microscopy technique enables fast, sensitive characterization for diamond material engineering and nanofabrication; as well as diamond-based sensing of strains applied externally, as in diamond anvil cells or embedded diamond stress sensors, or internally, as by crystal damage due to particle-induced nuclear recoils.
