Role of exchange interaction in nitrogen vacancy center based magnetometry
Role of exchange interaction in nitrogen vacancy center based magnetometry
We propose a multilayer device comprising a thin-film-based ferromagnetic heterostructure (FMH) deposited on a diamond layer doped with nitrogen vacancy centers (NVC's). We find that when the NVC's are in close proximity (1--2 nm) to the FMH, the exchange energy is comparable to, and may even surpass, the magnetostatic interaction …
