Influence of ferromagnetic electrodes on the resistive switching device based on NiO

DOI

Description

Metal-insulator transition (MIT) induced by the electric field has been intensively investigated owing to its potential for nano-sized resistance switching devices in the next generation as well as its simple device structure. Although the MIT has been reported in various oxides such as Mn oxide1), Gd oxide2), and Co-doped Ti oxide3), the microscopic origin of the phase transition is still controversial issue. It should be noted that some of the oxides showing the MIT include magnetic components, implying that the MIT is related to the transition of the spin state. To explore the correlation between the MIT and spin configuration, in the present study, we investigate the influence of the ferromagnetic electrode on the MIT.
