Abstract
Section titled “Abstract”Abstract Optimal conditions for creating shallow ensemble nitrogen-vacancy (NV) centers in a 12 C-enriched diamond were investigated. NV spin properties, created by implantation of 15 N + ions with 2−5 keV energies and 1 × 10 11 −1 × 10 13 ions cm −2 doses, were evaluated by Rabi contrast, longitudinal relaxation time T 1 , and spin-spin relaxation time T 2 (spin echo). The optimal NV conditions, yielding high-quality NV spins’ properties, usable for nanoscale NV-NMR (nuclear magnetic resonance), were confirmed as 3 keV and 1−3 × 10 12 ions cm −2 doses with the lowest estimated value of AC magnetic field sensitivity as 44 nT Hz -1/2 .
