摘要:
A probe, device, and methods for performing nuclear magnetic resonance (NMR) measurements on a suitable sample are provided. The probe includes a hyperpolarized tip positioned to cause a dipolar interaction between the tip and sample. The nuclear magnetic spin of a selected portion of the sample induces a modulation of tip magnetization, which is proportional to the local magnetization of the selected portion. An NMR device includes the probe, a radio frequency (RF) coil for manipulating spins in the sample and tip, and a means for detecting the modulation of tip magnetization. An RF pulse sequence selects the selected portion and allows detection of the modulation. The method for obtaining NMR data includes positioning the tip to induce the dipolar interaction; selecting the sample portion; modulating the tip magnetization in response thereto; and detecting the tip modulation. The device and method may be adapted to obtain NMR images and spectroscopy.
