[Auszug] During the past 18 months we have been cooling dilute solutions of 3He in 4He below 0.4 mK by adiabatic demagnetization of nuclear spins in copper1"4. Since the Kapitza coupling between metals and dilute 3He-4He solutions is very much worse than that between metals and pure 3He several improvements ...
