AbstractTransport properties of La 0.8Ba 0.2MnO 3 thin films deposited by the sol-gel method were investigated. It has been found that resistivity plateaus occurred in the ρ-T curves after application of a dc bias current over a critical value. A current of 200 μA could induce a huge resistance variation ∼1200% in these La 0.8Ba 0.2MnO 3 films near room temperature, demonstrating a colossal electroresistance effect. Such strange transport behavior suggests the formation of conductive filaments and that the multi-phase coexistence is sensitive to external stimuli. This phenomenon may find applications in sensing and logic devices. © 2012 Elsevier B.V. All rights reserved.
