[Fe(1 ML)/Pt(1 ML)] (001) monoatomic multilayers, equivalent to the L10 ordered phase, have been prepared by depositing alternate monoatomic layers of Fe and Pt. The surface flatness and the degree of layer ordering improve with increasing substrate temperature. The perpendicular magnetic anisotropy and Kerr rotation (λ = 633 nm) at room temperature increase with increasing degree of layer ordering. The highly ordered Fe/Pt monoatomic multilayers grown at 500°C show a very large perpendicular anisotropy, which is close to the magnetocrystalline anisotropy of FePt(L10) ordered alloy, and a high saturation Kerr rotation of 0.69°.
