Abstract.
Double perovskite Ba2FeMoO6 has been prepared by a wet chemistry method and its magnetocaloric effect has been studied. The Ba2FeMoO6 sample, consisting of crystallites with diameter of 130 nm and average aspect ratio of 15, exhibits a sharp magnetic transition. The maximum of the magnetic entropy change peaks at its Curie temperature (340 K), and a large magnetic entropy change (\(\sim\)1.54 J/kg K, or \(\sim\)0.081 J/mol (atoms) K) is obtained upon 10 kOe applied magnetic field change. For comparison, the magnetic properties of Ba2FeMoO6 prepared by a conventional solid-state reaction was also investigated.
