We found the large magnetocaloric effect (MCE) in La0.6Ca0.3Pb0.1MnO3 (sample No. 1), La0.7Ca0.2Pb0.1MnO3 (sample No. 2), and La0.7Ca0.1Pb0.2MnO3 (sample No. 3) perovskites, which were prepared by a conventional ceramic method. For a magnetic field change of 13.5 kOe, the magnetic entropy change (Delta S-M) reached values of 2.55, 2.53 and 3.72 J/kg K for samples Nos. 1, 2 and 3, respectively. Interestingly, the large Delta S-M was found to occur around 300 K for all samples investigated, which allows magnetic refrigeration at room temperature. These perovskites have the large magnetic entropy changes induced by low magnetic field change, which is beneficial for the household application of active magnetic refrigerant (AMR) materials.
