Type: article
Abstract: This study reports on the synthesis and characterization of Ga-rich MnGa thin films sputter-deposited onto Si/SiO2substrates. The investigation focuses on the effect of growth temperature on the formation of the chemically ordered L10crystal structure. Spectroscopic and microscopic evidence correlate the stoichiometry, crystal structure, and microstructure of the films to their magnetostatic properties and their microscopic magnetic structure. Our results reveal stoichiometric inhomogeneities in the films, which are composed of multiple crystal phases. The formation of the L10MnGa crystal structure is enhanced with increasing deposition temperature, which correlates directly with the emergence of magnetic domains and a significant increase in magnetic coercivity. By elucidating the interplay between stoichiometry, crystal structure, microstructure and the magnetic properties of MnGa films deposited onto Si/SiO2, rather than on monocrystalline substrates, this work contributes to the understanding of MnGa growth on amorphous substrates.
