Electric polarization loops are measured at room temperature on highly pure BiFeO3 single crystals synthesized by a flux growth method. Because the crystals have a high electrical resistivity, the resulting low leakage currents allow the authors to measure a large spontaneous polarization in excess of 100μCcm−2, a value never reported in the bulk. During electric cycling, the slow degradation of the material leads to an evolution of the hysteresis curves eventually preventing full saturation of the crystals.

• Some symmetry aspects of ferroics and single phase multiferroics* (2008, background): “The recently reported rapid degradation of ferroelectric hysteresis cycles of initially perfect single crystals of BiFeO3 (Lebeugle 2007 and Lebeugle et al 2007) was certainly caused by such mechanical interaction due to a too high ferroelastic shear angle (cf table 6).”
