Abstract
A method of detecting spins in a sample, includes exciting the spins of the sample by means of a radio-frequency or microwave electromagnetic pulse for flipping the spins, and detecting a noise signal produced by the return of the spins to equilibrium by means of a device for counting radio-frequency or microwave photons.
