摘要：

The dependence of magnetization on the applied magnetic field and temperature was measured carefully near their Curie temperature for polycrystalline perovskite-type manganese oxides La1-xNaxMnO3 (0.05 < X less than or equal to 0.20) prepared by sol-gel technique. The large magnetic entropy changes upon an application of a low magnetic field and the convenient adjustment of the Curie temperature make the perovskite-type manganese oxides useful for magnetic refrigerants in an extended high temperature range even at room temperature.
