Multifunctional features of perovskite-type ferro-manganite La0.5Ca0.5Mn0.5Fe0.5O3
Description
Characterization of the La0.5Ca0.5Mn0.5Fe0.5O3 material is reported, as well as the structural analysis, optical and magnetic response measurements, density of states and band structure calculations, in order to establish the types of interaction that give rise to the macroscopically observed physical properties. In addition to experimental techniques, the approach of the paper applies theoretical methods for the study of the electronic characteristics of the material, as those based on density functional theory (DFT) have been shown to be appropriately useful in understanding the properties of perovskite family materials.

Polycrystalline samples of La0.5Ca0.5Mn0.5Fe0.5O3 were synthesized using the standard solid-state reaction method. High-purity La2O3, CaCO3, Mn2O3 and Fe2O3 (purity >99.95%) were accurately weighed in the stoichiometric ratio and mixed in an agate mortar for 3 hours. The resulting mixture was loaded into an alumina crucible and subjected to calcination at 1150 °C for 48 h, and then annealed at 1150 °C for another 48 h after further grinding for 30 min.
