    Abstract

    Magnetic entropy change of La 0.75 Ca 0.25 MnO 3 with different particle size has been investigated. Magnetic entropy change ∼ 4.7 J/kg K larger than that of Gd has been observed at 224 K under a magnetic field 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 temperature.
