Abstract: Multiferroic devices that can switch magnetization with electric field at room temperature are desirable, but in BiFeO3 the required direct 180-degree switch is thermodynamically forbidden; here it is shown that such switching is possible because the kinetics of the switching process favours a two-step sequence of partial switching.
