Abstract :
We demonstrate that ferroelectric (FE) domain switching induces a nonvolatile tuning of the magnetic and electric properties in La0.6Ca0.4MnO3 (LCMO)/Pb(Mg1/3Nb2/3)O3-PbTiO3 heterostructure. The FE domain switching in the substrate contributes to an in-plane strain that changes the spin exchange coupling in the LCMO layer, and therefore results in a nonvolatile magnetization difference of up to -17.5% at zero external magnetic field, as well as a nonvolatile resistance difference of up to 20.3%. This nonvolatility of the modulation effect on the magnetic and electric properties by an electric field demonstrates great potential for the applications of magnetic and electric devices.
