The phase diagram of the betaine arsenate-phosphate mixed crystal system by mea...
Lanceros-Méndez, S.; Köhler, M.; Schaack, G.; Klöpperpieper, A.The ferroelectric (FE) betaine arsenate (BA) and the antiferroelectric (AF) betaine phosphate (BP) are structurally very closely related and mixed crystals of BAxBP1-x can be grown over the whole concentration range. The concentration (x) – temperature (T) – pressure (P) phase diagram of the system is characterized by a transition from an AF to a FE phase along with the appearance of some mixed regions on chang...
Ferroelectric/antiferroelectric phase coexistence in the intermediate concentra...
Lanceros-Méndez, S.; Mendes, J. A.; Köhler, M.; Schaack, G.Temperature and frequency dependent hysteresis loop measurements have been carried out along the phase diagram of ferroelectric (FE) betaine at-senate (BA) and antiferroelectric (AF) betaine phosphate (BP) mixed crystal system (BA(x)BP(1-x)). Coexistence regions characterized by competing ferro- and/or antiferroelectric interactions are detected by multiple hysteresis loops.
