Magnetization reversal assisted by the inverse piezoelectric effect in Co-Fe-B/ferroelectric multilayers

Abstract

We investigate magnetization reversal assisted by electric fields in a Co(40)Fe(40)B(20)/Co/Pd multilayer with soft perpendicular anisotropy deposited onto an epitaxial piezoelectric layer. Both the nucleation and depinning magnetic fields show a strong reduction of up to 30% under the application of an electric field.

These results show good prospects for assisting the switching processes in ultra-low-power spintronic devices.
