This paper reanalyzes the low temperature nuclear quadrupole resonance (NQR) experiments in La(1.875)Ba(0.125)CuO(4) by Hunt et al. [Phys. Rev. B 64, 134565 (2001)] in an attempt to determine the dimensionality of spin modulations in this…
We demonstrate electrical detection of the $^{14}$N nuclear spin coherence of NV centers at room temperature. Nuclear spins are candidates for quantum memories in quantum-information devices and quantum sensors, and hence the electrical…
Optically-probed nitrogen-vacancy (NV) quantum defects in diamond can detect nuclear magnetic resonance (NMR) signals with high-spectral resolution from micron-scale sample volumes of about 10 picoliters. However, a key challenge for NV-NMR…
