Using atomistic Monte Carlo simulations, we investigated the impact of the\ninterface on the structural properties of iron and copper (Fe/Cu) magnetic\nmultilayers grown by Vorono "i diagram. Interest in magnetic multilayers has\nrecently emerged as they are shown to be promising candidates for magnetic\nstorage media, magneto-resistive sensors, and personalized medical treatment.\nAs these artificial materials show large differences in properties compared to\nconventional ones, many experimental and theoretical works have been dedicated\non shedding light on these differences and tremendous results have emerged.\nHowever, little is known how the interfaces influence the structure of the\nlayers around them. By a numerical approach, we show that the structure of each\nlayer depends on its thickness and the interface morphology. The Fe and Cu\nlayers can adopt either the body-centered-cubic (bcc) or face-centered-cubic\n(fcc) structure, while the interface can assume amorphous, bcc, fcc, or a\nmixture of bcc and fcc structures depending on the layer thicknesses. These\nresults are in good agreement with the experiments. They could be helpful in\nunderstanding effects such as giant magneto-resistance from the structural\nviewpoint.\n
