SEED NSF-DMR11-21053 Probing spin and charge on the nanoscale Schematic of diamond-based scanning probe magnetometer Confocal microscope NV Tip (far away) We are building a scanning probe microscope to study spin and charge on the nanoscale. The magnetic sensing element is a nitrogen-vacancy center (NV) in diamond, which should afford single electron spin sensitivity with 10 nm spatial resolution. Gd spins on glass AFM tip δ-doped Diamond NV sensor 532 nm Tip (over NV) Confocal fluorescence images showing relative locations of NV and Gd-functionalized tip T1 reduced by ~1000x with nanoscale control NV
