“…The multilayer peaks Pt/FCS (111) also grow more defined with t Pt increasing and the peak becomes the most distinct when Pt thickness is 2 nm. Previous studies have proved that different Pt orientations result in different magnetic anisotropy between Pt/Co 2 FeAl; while Pt(111) can induce PMA in the Pt/Co 2 FeAl interface, Pt(001) deteriorates PMA . The XRD diffraction spectra for n = 2 (Figure d) shows the strong Pt(111) reflections in the same intensity as the n = 9 stacks but exhibit much weaker FCS/Pt multilayer peaks and Pt(222) peaks at 86°.…”

This confirms our hypothesis that Pt buffer is (111) oriented.…”

We report a large interfacial perpendicular magnetic anisotropy (PMA) in [Fe2CoSi/Pt] n (FCS/Pt) multilayers deposited on thermally oxidized Si substrates. A maximum anisotropy energy density, K u, of 2.64 Merg/cm3 is achieved with an optimized stack. We are able to tune the PMA by adjusting the Pt and FCS film thicknesses and number of periods of the multilayer structure, as these significantly affect the lattice structure of FCS/Pt stack. Both high-resolution transmission electron microscopy and structural relaxation of the atomistic model using first-principles calculations reveal that while the multilayer structure assumes a monoclinic structure (α = 84°), the FCS films undergo a local orthorhombic distortion from the bulk structure due to the strain imposed by the FCS/Pt interface. By analyzing the orbital-resolved density of states of the system, we propose that both the orthorhombic distortion of the FCS and orbital interactions between interface Pt and Fe atoms are responsible for the high PMA. For the first time, a large interfacial PMA is demonstrated in the Fe-based Heusler/Pt multilayer structure with underlying mechanisms discussed via both experiments and first-principles calculations. Thus, we have shown that there is great potential in strain-enhanced FCS/Pt multilayers in future applications in spintronic devices.
