Abstract: Since palladium is a nearly ferromagnetic paramagnet, a strong electric field in the layered metal/insulator/metal nanostructure can convert it into a ferromagnetic state. The electronic structure calculation of modified solid nanocell Pd/BaO/Au type under external electric field has performed. The structure relaxation was taken into account. The difference of Pd electronic structure was analyzed in structures with Pd and Au slabs in external electric field. The calculation of nanocell was done in spin-orbit and spin-polarized cases. It has been shown that in a structure with alternating layers of palladium and a more electronegative metal, e.g. gold, the threshold electric field required for the transition to a ferromagnetic state is reduced.

Keywords: magnetism, nanostructure, density functional theory, induced electric field, density of state.
