Landau mean-field analysis and estimation of the spontaneous magnetization from magnetic entropy change in La0.7Sr0.3MnO3 and La0.7Sr0.3Mn0.95Ti0.05O3

In this work, we present the research results of magnetocaloric property and spontaneous magnetization on polycrystalline compounds of La0.7Sr0.3MnO3 and La0.7Sr0.3Mn0.95Ti0.05O3. The magnetic entropy change ΔSM has been determined by two methods: Maxwell relation and Landau theory. The analysis of...
