Abstract Using in situ electric-field-modulated anisotropic magnetoresistance measurement, a large reversible and non-volatile in-plane rotation of magnetic easy axis of $\sim$35$^{\circ}$ between the positive and negative electrical poling states is demonstrated in Co$_{40}$Fe$_{40}$B$_{20}$/(001)-cut Pb(Mg$_{1/3}$Nb$_{2/3}$)O$_{3}$-0.25PbTiO$_{3}$ (PMN-PT). The specific magnetoelectric coupling mechanism therein is experimentally verified to be related to the synchronous in-plane strain rotation induced by 109$^{\circ}$ ferroelastic domain switching in the (001)-cut PMN-PT substrate.
