Web29 apr. 2024 · Nuclear spins can be measured for certain atoms through their fluorescence signals. These signals can also determine the spins of the fluorescent atom’s neighbors. Until now that had been demonstrated only in “dilute nuclear-spin baths,” in which most of the atoms have an even number of protons and neutrons and, therefore, zero spin. WebWhen electrons flow through the device, the electron spins in turn act back on the nuclear spin bath, and cause dynamical nuclear polarization. This sometimes leads to a striking bistable behavior. See also the press release or the article [Science 309, 1346 (2005)].
