Fast and sensitive detection of hemoglobin and other paramagnetic species using coupled charge and spin dynamics in strongly fluorescent nanodiamonds
F. Gorrini, R. Giri, C. E. Avalos +9
Sensing of a few unpaired electron spins, such as metal ions and radicals, is a useful but difficult task in nanoscale physics, biology, and chemistry. Single nitrogen-vacancy (NV)…
Multi-spin-assisted optical pumping of bulk 13C nuclear spin polarization in diamond
Daniela Pagliero, K. R. Koteswara Rao, Pablo R. Zangara +11
One of the most remarkable properties of the nitrogen-vacancy (NV) center in diamond is that optical illumination initializes its electronic spin almost completely, a feature that…
Optically-pumped dynamic nuclear hyperpolarization in C enriched diamond
Anna J. Parker, Keunhong Jeong, Claudia E. Avalos +4
We investigate nuclear spin hyperpolarization from nitrogen vacancy centers in isotopically enriched diamonds with C concentrations up to 100%. C enrichment leads to…
Room-Temperature in situ Nuclear Spin Hyperpolarization from Optically-Pumped Nitrogen Vacancy Centers in Diamond
Jonathan P. King, Keunhong Jeong, Christophoros C. Vassiliou +5
We report bulk, room-temperature hyperpolarization of 13C nuclear spins observed via high-field nuclear magnetic resonance (NMR). The hyperpolarization is achieved by optical pumpi…
Optically detected nuclear quadrupolar interaction of 14N in nitrogen-vacancy centers in diamond
Chang S. Shin, Mark C. Butler, Hai-Jing Wang +5
We report sensitive detection of the nuclear quadrupolar interaction of the 14N nuclear spin of the nitrogen-vacancy (NV) center using the electron spin echo envelope modulation te…
Optically Detected Cross-Relaxation Spectroscopy of Electron Spins in Diamond
Hai-Jing Wang, Chang S. Shin, Scott J. Seltzer +3
The application of magnetic resonance (MR) spectroscopy at progressively smaller length scales may eventually permit "chemical imaging" of spins at the surfaces of materials and bi…
Suppression of electron spin decoherence of the diamond NV center by a transverse magnetic field
Chang S. Shin, Claudia E. Avalos, Mark C. Butler +5
We demonstrate that the spin decoherence of nitrogen vacancy (NV) centers in diamond can be suppressed by a transverse magnetic field if the electron spin bath is the primary decoh…
Sensitive Magnetic Control of Ensemble Nuclear Spin Hyperpolarisation in Diamond
Hai-Jing Wang, Chang S. Shin, Claudia E. Avalos +4
Dynamic nuclear polarisation, which transfers the spin polarisation of electrons to nuclei, is routinely applied to enhance the sensitivity of nuclear magnetic resonance; it is als…
Room Temperature Operation of a Radiofrequency Diamond Magnetometer near the Shot Noise Limit
Chang S. Shin, Claudia E. Avalos, Mark C. Butler +8
We operate a nitrogen vacancy (NV-) diamond magnetometer at ambient temperatures and study the dependence of its bandwidth on experimental parameters including optical and microwav…
