Abstract
A new method of producing temperatures below 1°K is considered. It utilizes the fact that the entropy of certain paramagnetic salts is increased by the isothermal application of a magnetic field, so that, conversely, adiabatic magnetization should produce cooling. The factors limiting the temperatures which can be reached are discussed, and some suitable classes of salts proposed.
