Title: Electric field induced modification of magnetic properties in Co{sub 2}Si{sub 2} multilayers

Effects of an external electric field on the magnetization and magnetocrystalline anisotropy (MA) in Co{sub 2}Si{sub 2} multilayers are investigated by first-principles calculations. The results demonstrate that, due to the hybridization between the Si-2p orbitals and the Co-3d orbitals, the magnetic moment of the Co{sub 2}Si{sub 2} supercell changes non-linearly with external electric field and the behavior of band structures near the Fermi energy could be explained within near-rigid-band model. Moreover, spin-polarized charge redistribution leads to spin reorientation and the MA is not proportional to the orbital moment anisotropy under the external electric field.
