Nuclear demagnetization for ultra-low temperatures
Cryogenics, 2014 Nuclear demagnetization is one of the most successful methods of cooling an appreciable amount of matter to the lowest temperatures. The principle of nuclear demagnetization is the same as that of the adiabatic demagnetization of a paramagnetic salt; however, there is a significant difference in practice. This article focuses on nuclear demagnetization
