We have fabricated epitaxial Fe/NaF/MgO multilayers and characterized their surface crystallinity and magnetic property. We observe that the 0.1 nm NaF insertion increases the interfacial perpendicular magnetic anisotropy, while the thicker NaF insertion weakens it. We will discuss the influence of electronegativity and lattice matching on the PMA energy.
