Abstract

The magnetocaloric properties of La1.25Sr0.75MnCoO6 (LSCM) manganites that were synthesized at 750 and 1,300 °C have been investigated. It is found that magnetic entropy change distribution of the LSCM is much more uniform than that of gadolinium. This feature is desirable for an Ericson-cycle magnetic refrigerator. It is suggested that LSCM can be used in an active magnetic regenerative nitrogen liquefier to cool nitrogen gas from room temperature to 77 K.
