The crystal structure, magnetic properties and magnetoelectric effect were measured. The experimental results indicate that, the thin film presents obvious electric-field modulation effect on magnetic properties. More- over, this modulation effect is non-volatile and presents temperature stability, which is benefit for the fields including information memory and sensor. Also, the modulation mechanism was inves- tigated. For example, the electric field modulation effect on magnetic properties in Ni/PMN-PT thin film is attributed to the change of the magnetic anisotropy, which results from the ferroelec- tric polarizing induced-stress.
