Microwave-free wide-field magnetometry using nitrogen-vacancy centers
Joseph Shaji Rebeirro, Muhib Omar, Till Lenz +4
A wide-field magnetometer utilizing nitrogen-vacancy (NV) centers in diamond that does not require microwaves is demonstrated. It is designed for applications where microwaves need…
