Abstract Details

, Doctor of Philosophy, Case Western Reserve University, Physics.
In this thesis, we study the interaction between a ferromagnetic vortex and nitrogen-vacancy (NV) center spins in diamond at room temperature. The spin of a NV center has proven to be a promising qubit candidate due to its atomic size and long coherence times at room temperature. 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 NV spins with nanometer-scale resolution. We demonstrate that the vortex core can be driven in proximity to NV spins, inducing significant spin splitting. In addition, we find the magnetic field gradient produced from the vortex core is sufficient to address single NV spins. We demonstrate that the vortex can be driven on nanosecond timescales to sequentially address and coherent manipulate spins. We find the vortex acts as a MW amplifier that can coherently drive the NV spins, enhancing the Rabi oscillations by more than an order magnitude. Lastly, we find that the vortex reduces the NV spin lifetime when near the NVs. However, robust lifetimes can be maintained for specific situations, even when the vortex core is near the NVs.
