Helium stays in liquid form down to absolute zero temperature. Since the effects of quantum mechanics become particularly evident at low temperatures, helium is an ideal system for experimental studies of macroscopic quantum phenomena. One of the most remarkable of these is the transition into zero-viscosity superfluid phase. In case of fermionic helium-3 isotope, this transition occurs at temperatures below 0.003 K. In the low-temperature B phase of superfluid helium-3, the transport of both mass and magnetization occur without losses. The spin superfluidity gives rise to spontaneous coherent long-living precession of magnetization observed in nuclear magnetic resonance (NMR) experiments. The coherent precession can be described in term...
