Quantum sensors based on nitrogen-vacancy centers in diamond have emerged as a promising detection modality for nuclear magnetic resonance (NMR) spectroscopy owing to their micron-scale detection volume and non-inductive based detection. A remaining

Two new methods are presented for shimming dipole magnets intended for NMR. Both methods allow for very fine scale adjustment of the passive shim strength, in one case while the shim remains in the magnet. The first method utilizes magnetic ink print

The static magnetic susceptibility of the rf coil can substantially distort the field B0 and be a dominant source of line broadening. A scaling argument shows that this may be a particular problem in microcoil NMR. We propose coil extensions to reduc

An NMR shim coil design method that addresses the severe spatial constraints of miniaturized dipole magnets is introduced. The fundamental design element, a collection of straight wires, is shown to be sufficient for producing a complete set of shim

We demonstrate the first subkilogram permanent magnet and microcoil probe combination capable of 1H nuclear magnetic resonance spectroscopy with subparts-per-million resolution. The 1 T magnet with a weight of 685 g utilizes steel pole faces and flux

Microcoil probes enclosing sample volumes of 1.2, 3.3, 7.0, and 81 nanoliters are constructed as nuclear magnetic resonance (NMR) detectors for operation in a 1 tesla permanent magnet. The probes for the three smallest volumes utilize a novel auxilia

Nuclear magnetic resonance spin-lattice relaxation rates for 1H in quasicrystalline Ti45Zr38Ni17H x are presented as a function of temperature and hydrogen concentration x. The temperature dependence demonstrates that the relaxation is via interactio
