Applications

 

NV scanning probes can be used in a wide variety of experiments. The precise measurement of magnetic fields, coupled with a detailed AFM image that is recorded simultaneously allow for very accurate reconstructions of magnetic surfaces or electric currents that can be resolved in unseen nm-resolution.

The QZabre represents a new generation of scanning sensors that exploit quantum metrology to achieve unprecedented sensitivities combined with sub-50 nm spatial resolution. Key applications include the vector field analysis of magnetic nanostructures, quantitative analysis of current distributions, imaging of biomagnetic or bioelectric signals, and nanoscale thermometry. A further description about the working principle of scanning diamond magnetometry and its range of applications is given here.

The QZabre has been designed to support one specific application: Scanning quantum magnetometry experiments based on a single nitrogen-vacancy in diamond. Its application requires a combined optical and scanning probe microscope with a single photon detection capability. In addition, a microwave antenna and a suitable microwave generation are required. We are happy to provide suggestions on suitable equipment for your specific application.
