Figure 3

(a–c) P–E curves measured with E applied along the a axis at B=0 (a), 3 (b) and (c) 8 T. The first, second, third and fourth panels from the top denote the data at 4.6, 5.2, 7.1 and 8.7 GPa. (d) The spontaneous polarization Ps as a function of temperature at various magnetic fields and pressures.
