High-Resolution Nanoscale Solid-State Nuclear Magnetic Resonance Spectroscopy

Abstract

We present a new method for high-resolution nanoscale magnetic resonance imaging (nano-MRI) that combines the high spin sensitivity of nanowire-based magnetic resonance detection with high spectral resolution nuclear magnetic resonance (NMR) spectroscopy. By applying NMR pulses designed using optimal control theory, we demonstrate a factor of $500$ reduction of the proton spin resonance linewidth in a $(50\text{-nm}{)}^{\text{3}}$ volume of polystyrene and image proton spins in one dimension with a spatial resolution below $2\text{nm}$.
