Research Abstract

We prepared BiFeO_3/CoFe_2O_4 bilayer, and magnetic domain of CoFe_2O_4 was successfully reversed by an applying electric field to BiFeO_3 at room temperature. Our experimental plan was achieved 100%. Moreover, we could reduce the voltage by 1/20 using the vertical stacking structure, and small magnetic domain with 150 nm in diameter was successfully reversed in this project. This means that these research results are surpass to our expectation in first proposal
