  We fabricated Pb(Zr0.52Ti0.48)O3-NiFe2O4 composite films consisting of
randomly dispersed NiFe2O4 nanoparticles in the Pb(Zr0.52Ti0.48)O3 matrix. The
structural analysis revealed that the crystal axes of the NiFe2O4 nanoparticles
are aligned with those of the ferroelectric matrix. The composite has good
ferroelectric and magnetic properties. We measured the transverse and
longitudinal components of the magnetoelectric voltage coefficient, which
supports the postulate that the magnetoelectric effect comes from direct stress
coupling between magnetostrictive NiFe2O4 and piezoelectric Pb(Zr0.52Ti0.48)O3
grains.
