The coupling of ferroelectric and ferromagnetic order parameters in low dimension materials have been of great attention due to the potential electronic applications in future technology. In this report, by employing first-principles density-function-theory calculation without including spin-orbital coupling, we demonstrate that the magnetization of iron thin film increases in proportion to the external electric field. This intruging properties stems from the spin-dependent screening of the electric field which leads to spin imbalance of the excess surface charge. The result is in accordance with a predictive result including spin-orbital coupling published earlier. We suggest that the electrically controlled magnetism might be used in advanced magnetic and electronic devices. Keywords: magnetoelectrics, magnetic moments, induced charge, thin film, density functional theory.
