Typical evolution of resonance frequency is shown in Fig. 1 a, while Fig. 1 b depicts the Fast Fourier Transform (FFT) of this evolution. The sharp, dominant peak at frequency 1.47 Hz is clearly visible. This frequency corresponds to the Cold Head operation and can be measured independently as a temperature variation of the second stage of …

Whether it is a gas, a liquid, a solid, a powder, or a single crystal, at room or cryogenic temperatures, a material composed of spin-bearing particles can be a potential sample for magnetic resonance (MR) spectroscopy. 1–3 In the case of nuclear spins, a look at the periodic table of elements will tell us that almost all elements have spin …

This property enables the reformulation of the signal recovery as an SLR matrix completion problem, which includes performance guarantees. We also review fast algorithms that are comparable in complexity to current compressed sensing (CS) methods, which enable the framework's application to large-scale magnetic resonance (MR) recovery problems.

The term "nuclear magnetic resonance" (NMR) is hardly a world, but thanks to its usefulness in medicine, MRI—short for magnetic resonance imagining—is certainly a well-known term. In fact, MRI is simply the medical application of NMR. The latter is a process in which a rotating magnetic field is produced, causing the nuclei of ...
