Superfluid 3He A is a liquid ferromagnet

Research output: Contribution to journalArticlepeer-review


THE superfluid A phase of liquid 3He (see for example refs 1, 2) is often said to display orbital ferromagnetism3. This term generally seems to be meant metaphorically and to imply that this phase possesses a finite total orbital angular momentum in equilibrium3. I point out here that superfluid 3He A is in fact quite literally ferromagnetic, with a spontaneous magnetic moment which, although extremely small on the scale of ordinary ferromagnets (∼ 10-11 Bohr magnetons per atom) is probably measurable and may indeed have some interesting experimental implications.
