Fast nanoscale addressability of nitrogen-vacancy spins via coupling to a dynamic ferromagnetic vortex
Abstract The core of a ferromagnetic vortex domain creates a strong, localized magnetic field, which can be manipulated on nanosecond timescales, providing a platform for addressing and controlling individual nitrogen-vacancy centre spins in diamond at room temperature, with nanometre-scale resolution. Here, we show that the ferromagnetic vortex can be driven …
