We demonstrated an electric field controlled exchange bias (EB) effect accompanied with
unipolar resistive switching behavior in the Si/SiO2/Pt/Co/NiO/Pt device. By applying certain
voltages, the device displays obvious EB in high-resistance-state while negligible EB in low-
resistance-state. Conductive filaments forming and rupture in the NiO layer but near the Co-
NiO interface are considered to play dominant roles in determining the combined resistive
switching and EB phenomena. This work paves a new way for designing multifunctional and …
We demonstrated an electric field controlled exchange bias (EB) effect accompanied with unipolar resistive switching behavior in the Si/SiO2/Pt/Co/NiO/Pt device. By applying certain voltages, the device displays obvious EB in high-resistance-state while negligible EB in low-resistance-state. Conductive filaments forming and rupture in the NiO layer but near the Co-NiO interface are considered to play dominant roles in determining the combined resistive switching and EB phenomena. This work paves a new way for designing multifunctional and nonvolatile magnetic-electrical random access memory devices.
