摘要: The coaction and competition between the ferroelectric field effect strain in Pr0.5Ca0.5MnO3 (PCMO) film/0.67Pb(Mg1/3Nb2/3)O3-0.33PbTiO3 crystal heterostructures were studied. Based on different types of resistance-electric hysteresis loops at various temperatures, it is clearly identified that dominates over for temperature T above charge-ordering TCO PCMO. With strong localization charge carriers < TCO, strongly competes with finally latter 0.8TCO. Moreover, poling-induced considerably enhanced by a magnetic field, demonstrating important role phase separation understanding such heterostructures.
