The magnetization behaviors have been investigated for La1-xPbxMnO3 (x = 0.1, 0.2, 0.3) alloys. The Curie temperature increased from 195 to 352 K with increasing Pb concentration. A large magnetic entropy change ( A SM ), which is calculated from H versus M curves associated with the ferromagnetic-paramagnetic transitions, has been observed. The maximum A SM of La0.8Pb0.2 MnO3 was 1.22 J/kg K at 294 K for an applied field of 1.5 T. Adiabatic temperature change (ΔTad) was measured directly by a special cryostat. The maximum ΔTad of La0.7Pb0.3MnO3 was 1.00 K at 352 K for an applied field of 2 T.
