In collaboration with the group of Lasers, Nanostructures and Materials Processing we have initiated a intense collaboration aimed at studying the growth of magnetite thin films on various oxide substrates either polycrystalline (SiO2) or single crystal (SrTiO3 (100) and others). We have studied the influence that the laser wavelength and the substrate temperature during deposition have on the stoichiometry and structural quality of the films formed and we have found that wavelengths in the infrared and substrate temperatures of 450 ° C give rise to magnetite films with the correct stoichiometry and with high structural quality. In addition, we are studying the influence that the deposition parameters and the nature of the substrate exert on the magnetic anisotropy observed in the films.
