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.
