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

We investigate magnetization reversal assisted by electric fields in a Co40Fe40B20/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. [ABSTRACT FROM AUTHOR]
