Structural analysis was performed by X-ray diffraction technique. Rietveld refinement of the experimental data revealed that these materials crystallize in a perovskite-type monoclinic structure (P21/n, space group #14) with alternating arrangement of Fe-Sn cations along the three crystallographic axes. The strongly granular character of the surface of the material was observed by scanning electron microscopy micrographs. X-ray energy dispersive spectra exhibited a close correspondence of the composition of the samples with that expected from their stoichiometric formula. Magnetic characterization in the temperature regime 50 K < T < 325 K and applied fields up to 30 kOe suggests the occurrence of a ferromagnetic ordering with Curie temperature TC = 204 K. Diffuse reflectance spectra revealed the semiconducting characteristic of the CaLaSnFeO6 double perovskite with a bandgap of Eg = 2.33 eV. To establish the origin of the magnetic interactions, electronic structure calculations were performed in the vicinity of the Fermi level by means of the Density Functional Theory. These properties generate technological expectations in the spintronics industry for the production of information storage devices on magnetic media based on polarized spin currents such as spin valves and magnetic transistors. date: 2025-03-01 date_type: published publisher: Springer Science and Business Media LLC official_url: https://doi.org/10.1007/s10948-025-06902-1 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2365582 doi: 10.1007/s10948-025-06902-1 lyricists_name: Holmes, Stuart lyricists_id: SNHOL99 actors_name: Holmes, Stuart actors_id: SNHOL99 actors_role: owner full_text_status: public publication: Journal of Superconductivity and Novel Magnetism volume: 38 article_number: 100 issn: 1557-1939 citation: Moya, XA Velásquez; Fajardo, JC Rincón; Barragán, SG Posada; Peña, SJ Niño; Crisolo, TN Quispe; Sánchez, A Moreno; Carreño, AN Morales; ...
