Voltage-modified magneto-optical Kerr effect (MOKE) is widely used to describe the converse magnetoelectric (ME) effect in the ferroelectric/ferromagnetic (FE/FM) heterostructures. However, the applied voltage can possibly give rise to electro-optical effect of the FE layer, which would also affect the Kerr signals in the MOKE system. Here, we used an AC voltage to modulate the magnetization in the Ni/Pb(Zr0.52Ti0.48)O3(PZT) heterostructures with different pre-polarization states of the PZT layers to investigate the complexity of the Kerr signals. The results suggested that the voltage control of Kerr signal contained several origins; however, the strain-induced ME effect dominated in the ME effect in the heterostructures.
