Summary

As one of the most popular ultra-low temperature refrigeration methods, adiabatic demagnetization refrigerators (ADR) are widely used in space exploration projects. In order to obtain lower refrigeration temperature and larger refrigeration capacity, multi-stage ADRs are often adopted. Besides the choice of suitable magnetocaloric materials according to the different refrigeration temperatures at each stage, optimization between stages is also important. In this paper, a double-stage ADR in which GGG and CPA are used as refrigerants is taken as an example, to study the effects of the matching mass of magnetocaloric materials used and the initial temperature
