Opposite resistive switching characteristics for (Ba0.6Sr0.4)TiO3 thin films on Ir and Pt bottom electrode

► Little work has done on the RS property research for (Ba0.6Sr0.4)TiO3 thin film. ► We firstly found a remarkable RS property of epitaxially grown (Ba0.6Sr0.4)TiO3. ► The electrode plays an important role in the opposite RS process.
