Description
Summary:In this manuscript, the synthesis process of the CaLaTiFeO 6 material is shown. The crystallographic structure analysis reveals its monoclinic perovskite type nature (space group P2 1 /n, #14), its morphological strongly granular characteristics, its optical response yields its semiconducting character with a 0.61 eV bandgap and its ferromagnetic property at temperatures T > 350 K are reported. Likewise, calculations and analysis of the electronic properties are performed through density functional theory, which showed correlation with the experimental results. The results allow classifying the CaLaTiFeO 6 material as a ferromagnetic semiconductor at room temperature, making it a good candidate for the design of spintronic devices.
