“…Cross-relaxation features close to zero magnetic field have also been observed and can be deployed for highersensitivity microwave-free magnetometry [20,21]. The CR contrast was shown to be much larger in the zero-field limit [22,23], but all of the relaxation mechanisms have not been identified there.…”

We study relaxation processes in dipolar-coupled negatively charged nitrogen-vacancy (N-V − ) centers close to zero field. Specifically, we uncover regimes where flip-flop and double-flip processes, as well as mixing induced by local electric fields, play a significant role in N-V-N-V cross relaxation. Our results are relevant for understanding decoherence in many-body spin systems, as well as for high-sensitivity magneto-and electrometry with long-lived interacting solid-state spins. As a proof of principle, we present an orientation and microwave-free magnetometer based on cross relaxation.

“…This setup is comparable with those that can be found in the literature. [20,27] Correspondingly, the photocurrent is a function of the external magnetic flux density B DC and time t leading to a change in the detectable photocurrent according to the equation…”

An integrated magnetic sensor is designed and tested that utilizes the negatively charged nitrogen vacancy centers (NVC) in diamond as a magnetic field‐sensitive quantum material, which is accessed and readout solely optically. The compact sensor device features a side length of 10 mm and includes a small HPHT diamond slab, light‐emitting diode (LED) for excitation, and integrated photodiodes. A microwave‐free approach is used. With the device, DC sensitivity to magnetic fields of 49 nA mT−1 in the range of 5–50 mT is achieved. The sensor device is also capable of detecting very small magnetic fields: Magnetic field dependencies at very low flux densities in the μT range (zero‐magnetic field) show a characteristic fluorescence behavior revealing a sensitivity of 4.8 pA μT−1. Additionally, a ray‐tracing model is applied, to identify loss mechanisms in the setup. Using this device, an ultracompact, reliable, and industry‐ready package is made available for sensor developments in industry and academia.
