Abstract
In order to search for new materials for the application of magnetic refrigeration, the polycrystalline perovskite compound Nd2/3Sr1/3MnO3 was prepared by a solid-state method. The dependence of the magnetization on the applied field and temperature was measured near the Curie temperature. In terms of Maxwell’s equation, the temperature dependence of the absolute value of the isothermal magnetic entropy change |ΔSM| at various applied fields from 1 T to 5 T was determined. The results showed that a large magnetic entropy change was observed in this compound. The maximum magnetic entropy change |ΔSM max|can reach 3.25 J/kg K with an applied field of 1 T at the Curie temperature of 257.5 K, which equals that of Gd. At 5 T applied field, it is 7.57 J/kg K. Such good magnetocaloric properties make this compound a promising candidate for the application of magnetic refrigeration in the room-temperature range.
