Spatially resolved detection of complex ferromagnetic dynamics using optically detected nitrogen-vacancy spins
Spatially resolved detection of complex ferromagnetic dynamics using optically detected nitrogen-vacancy spins
We demonstrate optical detection of a broad spectrum of ferromagnetic excitations using nitrogen-vacancy (NV) centers in an ensemble of nanodiamonds. Our recently developed approach exploits a straightforward CW detection scheme using readily available diamond detectors, making it easily implementable. The NV center is a local detector, giving the technique spatial …
