چکیده انگلیسی
In this study, magnetic properties of exchange coupled nanocomposite multilayer thin films constructed alternately with magnetic hard Nd2Fe14B layers and soft α-Fe layers have been studied by micromagnetic finite element method (FEM). According to the results, effects of the thicknesses of layers and the magneto-crystalline anisotropy on the magnetic properties of the Nd2Fe14B/α-Fe multilayer systems have been estimated. On the other hand, the results have been analyzed by means of efficiency of interphase exchange coupling, which can be estimated by volume ratios of exchange coupled areas between magnetically hard Nd2Fe14B and soft α-Fe phase layers. The results show that the magnetic properties of exchange coupled Nd2Fe14B/α-Fe multilayer systems can be enhanced by efficient interphase exchange coupling between magnetically hard Nd2Fe14B layers and soft α-Fe layers.
