Effect of interfacial intermixing on the Dzyaloshinskii-Moriya interaction in Pt/Co/Pt
Effect of interfacial intermixing on the Dzyaloshinskii-Moriya interaction in Pt/Co/Pt
We study the effect of sputter-deposition conditions, namely substrate temperature and chamber base pressure, upon the interface quality of epitaxial Pt/Co/Pt thin films with perpendicular magnetic anisotropy. Here we define interface quality to be the inverse of the sum in quadrature of roughness and intermixing. We find that samples with …
