## Description

- description: To utilize highly spin-polarized Heusler alloys in practical spintronic
    devices, the realization of highly textured and structurally ordered polycrystalline
    thin films under limited annealing temperatures (TA) is critical. Compared to
    the natural [110]-texture of Heusler alloys, the [001]-texture is considered to
    be favorable for current-perpendicular-to-plane giant magnetoresistance devices
    due to the reduced lattice misfit with the face-centered-cubic (fcc) Ag spacer
    layers. In this study, we fabricated [001]-oriented polycrystalline Co2FeGa0.5Ge0.5
    (CFGG) Heusler alloy films epitaxially grown on a [001]-oriented polycrystalline
    Ag buffer layer on thermally oxidized Si substrate, and the microstructure of
    the [001]-oriented Ag/CFGG bilayer film was investigated in detail. The [001]-oriented
    Ag films were obtained by introducing N2 into Ar during the sputtering process.
    The [001]-oriented CFGG films exhibited smooth interfaces, the B2 ordering, and
    a high saturation magnetization close to the theoretical value under a relatively
    low annealing at TA = 300 ℃, which are critical for industrial applications such
    as read heads of hard disk drives.
