Abstract: Magnetocaloric effect (MCE) in fine-grained perovskite manganites of the type La0.67Ba0.33Mn1− x Sn x O3 (x=0.05, 0.1 and 0.15) were prepared by the solid-state method. The prepared samples remain single phase and exhibit paramagnetic to ferromagnetic phase transition (T C) at 340, 325 and 288K for x=0.05, 0.1 and 0.15, respectively. From the measured magnetization data of La0.67Ba0.33Mn1− x Sn x O3 compounds as a function of field (2T), the associated magnetic entropy change close to their respective Curie temperatures and the relative cooling power (RCP) have been determined. Large MCE has been obtained in all samples and |ΔSM |max reached the highest value of 2.49J/kgK at T C (288K) for the sample x=0.15, with H=2T. [Copyright &y& Elsevier]
