The role of step-size on the pressure phase diagram of BiFeO3

Abstract: bismuth ferrite (BFO) remains the most studied multiferroic as a result of room temperature electric and magnetic ordering. However, real world applications are limited due to high leakage currents, high capacitances and a complex magnetic order; undesirable properties for device applications. One way to improve these properties is to apply chemical pressure by adding dopant atoms. Understanding the BFO phase diagram as a function of pressure gives us a potential route to predict what properties or structures may be realised at certain levels of applied chemical pressure. We have been investigating the behaviour of BFO with applied pressure at room temperature and have observed a complex series of phase transitions. At low applied pressure we see anomolous behaviour which may arise due to small pressure steps. We wish to check this by collecting data with a larger pressure step.
