| Abstract: | The dependence of magnetic entropy of high temperature magnetic refrig-erator medium on the strength of external magnetic field and on the temperature is quantitafively investigated by means of ferromagnetic molecular field theory. A criterion for appropriately selecting working substances is presented. |
