The NMRduino is a compact, cost-effective, sub-MHz NMR spectrometer that utilizes readily available open-source hardware and software components. One of its aims to simplify the processes instrument setup data acquisition control make experimental spectroscopy accessible broader audience. In this introductory paper, key features potential applications are described highlight versatility both for research education.
Abstract Optically pumped magnetometers (OPMs) based on alkali-atom vapors are ultra-sensitive devices for dc and low-frequency ac magnetic measurements. Here, in combination with fast-field-cycling hardware high-resolution spectroscopic detection, we demonstrate applicability of OPMs quantifying nuclear relaxation phenomena. Relaxation rate dispersion across the nT to mT field range enables quantitative investigation extremely slow molecular motion correlations liquid state, time constants...
Atomic spin sensors offer precision measurements using compact microfabricated packages, placing them in a competitive position for both market and research applications. The performance of these sensors, such as the dynamic range, may be enhanced through magnetic field control. In this work, we discuss design miniature coils three-dimensional localized control by direct placement around sensor, flexible alternative to global approaches used previously. Coils are designed on biplanar...
We introduce a method for nondestructive quantification of nuclear spin polarization, relevance to hyperpolarized tracers widely used in magnetic resonance from spectroscopy vivo imaging. In bias field around 30 nT we use high-sensitivity miniaturized 87Rb-vapor magnetometer measure the generated by sample, as it is driven windowed dynamical decoupling pulse sequence that both maximizes lifetime and modulates polarization easy detection. demonstrate procedure applied 0.08 M [1–13C]-pyruvate...
The individual and coherent control of solid-state based electron spins is important covering fields from quantum information processing metrology to material research medical imaging. Especially for the in nanoscale networks, generation strong, fast localized magnetic crucial. Highly-engineered devices that demonstrate most desired features are found nanometer size writers hard disk drives (HDD). Currently, however, their operation, particular, comes at cost excessive noise. Here, we...
Photochemically induced dynamic nuclear polarization (photo-CIDNP) enables spin ordering by irradiating samples with light. Polarized spins are conventionally detected via high-field chemical-shift-resolved NMR (above 0.1 T). In this Letter, we demonstrate in situ low-field photo-CIDNP measurements using a magnetically shielded fast-field-cycling setup detecting Larmor precession atomic magnetometers. For solutions comprising mM concentrations of the photochemically polarized molecules,...
We discuss procedures for error-tolerant spin control in environments that permit transient, large-angle reorientation of a magnetic bias field. Short sequences nonresonant magnetic-field pulses laboratory-frame meridional plane are derived. These shown to have band-pass excitation properties comparable established amplitude-modulated, resonant used static, high-field resonance. Using these pulses, we demonstrate robust $z$ inversion proton ($^{1}\mathrm{H}$) nuclear resonance near Earth's
We demonstrate a method to quantify and manipulate nuclear spin decoherence mechanisms that are active in zero ultralow magnetic fields. These include (i) nonadiabatic switching of quantization axis due residual background fields (ii) scalar pathways through-bond couplings between 1H heteronuclear species, such as 2H used partially an isotopic substitute for 1H. Under conditions free evolution, relaxation can significantly limit polarization lifetimes thus the scope resonance procedures near...

Polarized spins are conventionally detected via high-field chemical shift-resolved NMR (above 0.1 T), however, of particular importance CIDNP processes occurring at relatively low fields (<50 mT). In this paper, we demonstrate in situ low-field photo-CIDNP measurements using shielded fast-field-cycling combined audio-frequency detection Larmor precession atomic...

We demonstrate a method to quantify and manipulate nuclear spin decoherence mechanisms that are active in zero ultralow magnetic fields. These include: (i) non-adiabatic switching of quantization axis, due residual background fields; (ii) scalar pathways through-bond couplings between $^1$H heteronuclear species, such as $^2$H used partially an isotopic substitute for $^1$H. Under conditions free evolution, relaxation can significantly limit polarization lifetimes thus the scope resonance...
