Abstract
In situ tuning effect on magnetism is often achieved by electric-field-induced inverse piezoelectric effect in ferromagnetic/piezoelectric structures. Here, we report on a non-volatile tuning of magnetic properties in Ni/Pb(Mg1/3Nb2/3)O3-PbTiO3 heterostructure. Both magnetization difference of up to 60% and coercivity difference of up to 23.2% are obtained by electric-field-induced the change of polar state in the substrate. This modulation effect is observed over a broad range of temperatures. The coincident changes of both magnetic properties and Raman scattering spectra with different polarization times for the heterostructure are detected, which indicates that the non-volatile tuning effect on magnetism is attributed to the change of the magnetic anisotropy result from the ferroelectric polarizing induced-strain.
