A series of Fe-Co alloys were produced at the atomic scale, onto 15 nm Cu buffer layers, using pulsed-current deposition. The relationship between saturation magnetization, Ms and lattice constant, a has been investigated. The effects of increasing stacking number (bilayer number) on the values of Ms and a have been examined. The alloys showed a maximum room temperature Ms of 240 emu / g at 25 at. Co. A study to the room temperature magnetic and microstructure analysis revealed that the increase in saturation magnetization strongly correlates with the lattice constant of the Fe-Co alloy.
