A strong consistency was observed between the theoretical and experimental curves of magnetizations and magnetic entropy changes, Δ S M ( T ) . Based on the mean-field generated Δ S M ( T ) , the substantial Temperature-averaged Entropy Change (TEC) values reinforce the appropriateness of these materials for use in magnetic refrigeration technology within TEC (10) values of 1 and 0.57 J∙kg1∙K1under 1 T applied magnetic field. %K Manganites %K Magnetization %K Magnetocaloric Effect %K Mean Field Model %K Simulation %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=134910
