Dynamic polarization of liquid 3He at high temperatures
Dyugaev A., Wagner I., Ovchinnikov Yu.
The possibility of achieving a dynamic polarization of 3He nuclei by a method involving a spin resonance of electrons or He+ ions in the interior of the liquid or compressed by an electric field below its surface is analyzed. The electrons and He+ ions act as paramagnetic impurities, through which angular momentum of the electromagnetic field is pumped into the spin subsystem of 3He nuclei. The properties of polarized 3He are predicted at high temperatures, at which particle-statistics effects are small, but the liquid is a quantum liquid.
