Abstract: A method of hyperpolarizing diamond particles includes applying a laser to a sample of the diamond particles, irradiating the diamond particles with a sweeping microwave to cause diamond polarization, shuttling the diamond particles through a magnetic field to detect 13C nuclei in the diamond particles, and relaying the diamond polarization to nuclear spins to one of a surrounding solid or fluid.

Abstract: Methods and systems for compensating for static magnetic field inhomogeneities during nuclear magnetic resonance detection are disclosed. Application of radio frequency pulses and/or magnetic field gradients may be used to correct for spin dephasing caused by the inhomogeneities. The methods and system may be used to improve signal-to-noise ratios in NMR and MRI systems where magnetic field inhomogeneity may have an effect.

Abstract: A probe, device, and methods for performing nuclear magnetic resonance (NMR) measurements on a suitable sample are provided. The probe includes a hyper polarized 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.
