The magnetic fields generated by spins and currents provide a unique window into the
physics of correlated-electron materials and devices. First proposed only a decade ago …

Magnetic resonance of single spins has flourished mostly because of the unique properties
of the NV center in diamond. This review covers the basic physics of this defect center …

Nitrogen-vacancy (NV) defect centers in diamond are promising solid-state magnetometers.
Single centers allow for high-spatial-resolution field imaging but are limited in their magnetic …

Abstract Magneto-optical (MO) effects, viz. magnetically induced changes in light intensity or
polarization upon reflection from or transmission through a magnetic sample, were …

The readout of negatively charged nitrogen-vacancy centre electron spins is essential for
applications in quantum computation, metrology and sensing. Conventional readout …

Large-scale quantum communication networks require quantum repeaters due to the signal
attenuation in optical fibers. Ideal quantum repeater nodes efficiently link a quantum memory …

Devices relying on microwave circuitry form a cornerstone of many classical and emerging
quantum technologies. A capability to provide in-situ, noninvasive, and direct imaging of the …

We demonstrate a robust, scale-factor-free vector magnetometer, which uses a closed-loop
frequency-locking scheme to simultaneously track Zeeman-split resonance pairs of nitrogen …

Nuclear magnetic resonance (NMR) spectroscopy is a widely used tool for chemical
analysis and molecular structure identification. Because it typically relies on the weak …

Magnetic microscopy of malarial hemozoin nanocrystals is performed by optically detected
magnetic resonance imaging of near-surface diamond nitrogen-vacancy centers. Hemozoin …
