Experimental magnetic-semiconductor features of the theoretically half-metallic perovskite CaLaTiFeO6

Abstract In this manuscript, the synthesis process of the CaLaTiFeO6 material is shown. The crystallographic structure analysis reveals its monoclinic perovskite type nature (space group P21/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 CaLaTiFeO6 material as a ferromagnetic semiconductor at room temperature, making it a good candidate for the design of spintronic devices.
