摘要：

A phase transition is usually accompanied by an enormous change in physical properties, which shows great potential in future information storage technologies if it can be tuned artificially. In this work, the metastable state La0.67Sr0.33MnO3 was incorporated into the ferroelectric BaTiO3 (BTO) to achieve metastable state multiferroic heterostructures. A temperature dependent volatile electroresistance (ER) was discovered. The duration of the volatile ER first increases with the increasing temperature and then decreases. This phenomenon is related to the ferroelectric phase transition of the BTO substrate. Our results show that the mediation of metastable states is a promising way to achieve a large modulation of physical properties in artificial structures. Published under license by AIP Publishing.
