| 초록 | In this paper, we have studied structural and magnetocaloric properties of La 0.8 Sr x Ca 0.2-x MnO 3 system with x = 0.05, 0.1 and 0.15. X-ray diffraction (XRD) indicates that samples with x = 0.05 and x = 0.1 crystallize in an orthorhombic structure in Pnma space group, whereas the sample with x = 0.15 crystallize in the rhombohedral structure with R3@?c space group. The field dependence of magnetocaloric properties of manganite La 0.8 Sr x Ca 0.2-x MnO 3 undergoing first order phase transition is investigated using a phenomenological model. The magnetic entropy change of the samples varies from 1.01 J/kg K for x = 0-1.57 J/kg K for x = 0.15 under the applied magnetic field of 12 kOe. These results indicate that the present compounds are one of candidate materials for magnetic refrigerators near room temperature. |
