Diamond magnetometer enhanced by ferrite flux concentrators
Ilja Fescenko, Andrey Jarmola, Igor Savukov +6
Magnetometers based on nitrogen-vacancy (NV) centers in diamond are promising room-temperature, solid-state sensors. However, their reported sensitivity to magnetic fields at low f…
Principles and Techniques of the Quantum Diamond Microscope
Edlyn V. Levine, Matthew J. Turner, Pauli Kehayias +6
We provide an overview of the experimental techniques, measurement modalities, and diverse applications of the Quantum Diamond Microscope (QDM). The QDM employs a dense layer of fl…
Imaging crystal stress in diamond using ensembles of nitrogen-vacancy centers
P. Kehayias, M. J. Turner, R. Trubko +5
We present a micrometer-resolution millimeter-field-of-view stress imaging method for diamonds containing a thin surface layer of nitrogen vacancy (NV) centers. In this method, we…
Two-dimensional nuclear magnetic resonance spectroscopy with a microfluidic diamond quantum sensor
Janis Smits, Joshua Damron, Pauli Kehayias +7
Quantum sensors based on nitrogen-vacancy centers in diamond have emerged as a promising detection modality for nuclear magnetic resonance (NMR) spectroscopy owing to their micron-…
