| Abstract | The magnetocaloric effect and magnetization behavior have been analyzed in the double-perovskite La 0.7 Ba 0.3 Mn 1-X Fe X O₃ compound with the sintering temperature at 1273 K. Samples were fabricated by the conventional solid-state reaction method. X-ray diffraction measurement revealed that all the samples had a single phase in orthorhombic. Detailed investigations of the magnetic entropy behavior of the samples were discussed with the variation of TC. The magnetic entropy changes, ΔS M of approximately 0.36-1.14 J/㎏ K were obtained in the temperature range of 145-350 K for the La 0.7 Ba 0.3 Mn 1-X Fe X O₃ compound. The enhancement of the magnetic entropy change is believed to be due to changes in the microstructure, which changes the magnetic part of the entropy of a solid around the magnetic ordering temperature. |
