AbstractSingle-phase polycrystalline samples of La0.8-xNdxNa0.2MnO3 (x = 0.00, 0.05, 0.10, 0.15 and 0.20) were prepared by the sol-gel method. Investigations of Curie temperature and magnetic entropy change were carried out in the temperature range 240-340 K and magnetic field range 0-1 T. It was found that the Curie temperature T-C decreases with increasing x, and that the maximum magnetic entropy change Delta S-M, for x = 0.20, is 0.3692 J/mol K near the temperature 295 K. The results suggested that these perovskite manganites have some appropriate properties for a good candidate as magnetic refrigeration in the room temperature range. (c) 2006 Elsevier Ltd.
