We report on the design of a single-chip X-band pulsed ESR detector (0.7 mm²), and results of single pulse, Hahn echo, two echoes, Carr-Purcell, and inversion recovery echo measurements at room temperature. We measured 8×10⁷ spins/Hz^(1/2) spin sensitivity on a 0.1 nL sensitive volume, with <100 mW power consumption.

NMRduino is a sub-MHz NMR spectrometer designed unsparingly for minimum complexity, providing low-entry-barrier-NMR for beginners and those who wish to build custom hardware. Utility ranges from exploration of basic NMR concepts such as phase cycling and coherence selection to advanced experimental control including low-frequency, low-field parahydrogen-induced hyperpolarization and spin decoupling.

In this work we present ways to minimize the perturbation of the applied magnetic field by optimizing solid-state NMR probe structures. This is achieved by a combination of simulations and experiments, which take susceptibilities of all parts in the NMR probe into account to then study the net effect upon the sample. Based on those results, modifications to NMR probes can be made, to minimize unwanted contributions. The smaller the perturbation of the applied magnetic field, the narrower the observed possible linewidth and the higher the resolution of the experiment.
