Hooray, an excuse to go on and on about spin noise! Predicted correctly by Bloch in 1946
A clip of text: “Even in the absence of any orientation by an external magnetic field one can expect in a sample with N nuclei of magnetic moment u to find a resultant moment of the order sqrt(N)*\mu because of statistically incomplete cancellation. This moment, however, would naturally be very small and in samples of normal size will be greatly increased as soon as the nuclei have found their equilibrium distribution in a field of a few thousand Gauss which, at the same time, will bring their Larmor precession into the convenient radiofrequency range.”

In honor of #ENCISMAR2025, I thought I would share our most recent foray into high-field NMR. Variable field, position-based shimming, and DNP using a tunable microwave cavity
