Abstract
In magnetic refrigeration wherein a magnetic Ericsson cycle or a magnetic Stirling cycle is realized, the present invention forms a heat path by which heat of a magnetic working substance at an isofield stage of high magnetic field or an isomagnetization stage of high magnetization is given to the magnetic working substance at an isofield stage of low magnetic field or an isomagnetization stage of low magnetization.
