Abstract
Magnetic entropy change of La0.75Ca0.25MnO3 with different particle si ze has been investigated. Magnetic entropy change similar to 4.7 J/kg K larger than that of Gd has been observed at 224 K under a magnetic f ield of 1.5 T in comparatively big particles. This phenomenon of large magnetic entropy change indicates that the perovskite-type manganese oxides have potential applications for magnetic refrigerants in high t emperature.
