Abstract

We propose an adiabatic magnetization process for cooling a Fermi electron gas to ultra-low temperatures as an alternative to the known adiabatic demagnetization mechanism. We show via a new adiabatic equation that at the constant density the increase of the magnetic field leads to the temperature decrease as T ~ 1/H². This process is identified in our numerical calculations, in which we also recover the adiabatic demagnetization mechanism for certain range.
