Abstract
${\text{LuFe}}_{2}{\text{O}}_{4}$ exhibits multiferroicity due to charge order on a frustrated triangular lattice. We find that the magnetization of ${\text{LuFe}}_{2}{\text{O}}_{4}$ in the multiferroic state can be electrically controlled by applying voltage pulses. Depending on with or without magnetic fields, the magnetization can be electrically switched up or down. We have excluded thermal heating effect and attributed this electrical control of magnetization to an intrinsic magnetoelectric coupling in response to the electrical breakdown of charge ordering. Our findings open up an effective way toward electrical control of magnetization.
