Change of magnetisation M for three sweeps of the electric field with \(0\le E\le 8\,\text{kV}/\text{cm}\) at 368 K and μ₀ H = 0.1 T. The first sweep is marked red and shows a virgin effect, whereas all sequential field sweeps lead to a reversible change of the magnetisation. (a) shows the M(E)-data, whereas in (b) M is plotted in dependency of the measurement sequence for better visibility of the reproducibility. The y-axis is identical for (a) and (b).
