چکیده انگلیسی
We have investigated the validity and usefulness of the theoretical modeling in La0.6Pr0.1Ba0.3MnO3 perovskite based on the Landau mean-field analysis of the magnetic-entropy change (âÎSM). An excellent concordance is found between the (âÎSM) values estimated by Landau theory and those obtained using the classical Maxwell relation. In order to estimate the spontaneous magnetization Mspont(T) at a given temperature, we used the mean-field theory by analyzing the ((âÎSM) vs. M2) data. The obtained Mspont(T) values are in good agreement with those found from the classical extrapolation from the (H/M vs. M2) Arrott curves, confirming that the magnetic entropy is a valid approach to estimate the spontaneous magnetization in our system.
