(a) Magnetization as a function of electric field at 100 K showing the M − E hysteresis loop. The inset shows the M–H hysteresis at low magnetic fields. (b) Four magnetization levels controlled by applying electric field in a repeated sequence of −1 MV/m → 0 → 1 MV/m → 0. No bias magnetic field is needed.
