Abstract

We present a scanning nuclear-spin resonance (NSR) method that incorporates resistive detection with electric-field induced NSR locally excited by a scanning metallic probe. In the quantum-Hall effect breakdown regime, NSR intensity mapping at both the fundamental NSR frequency f_75As and twice the frequency 2f_75As demonstrates the capability to probe the distribution of nuclear polarization, particularly in a semiconductor quantum well. We find that f_75As NSR excitation drives not only local NSR but also spatially overlapped nonlocal NSR, which suppresses the maximum intensity of local NSR, while the 2f_75As NSR yields purely local excitation conferring a larger intensity.
