Development of High Field Optically Detected Magnetic Resonance

ORAL

Abstract

A nitrogen-vacancy (NV) center in diamond possesses a unique electronic structure enabling single spin sensing through optically detected magnetic resonance (ODMR). Electron spin resonance (ESR) conducted through a single NV center is promising for the improvement of ESR spin sensitivity to single spin levels [1]. Here, we discuss a platform for nanoscale NV-based ESR at high magnetic fields. We present the development of a high-field ODMR system consisting of a high-frequency excitation component, superconducting magnet, NV detection system, microscope system and sample stage. We also plan to implement the capability of pulse shaping to increase the excitation bandwidth, consequently improving the signal-to-noise ratio. Double electron-electron resonance measurements of a single NV center at high magnetic fields is also discussed.
