Magnetoelectric effect in Pb(Zr0.95Ti0.05)O3 and CoFe2O4 heteroepitaxial thin film composite
Abstract Multiferroic epitaxial films, include SrRuO3/Pb(Zr0.95Ti0.05)O3/CoFe2O4 has been successfully deposited on SrTiO3 substrate by pulsed-laser deposition technique. The results show that the prepared films exhibit a single phase. The Pb(Zr0.95Ti0.05)O3 (PZT) film was highly textured with (100) orientation and gives good ferroelectric properties with saturated polarization of 15μC/cm2. The magnetic coercivity of CoFe2O4 film on Pb(Zr0.95Ti0.05)O3 has been dampened to 0.9kOe. The anisotropic magnetically behavior of CoFe2O4 film was changed to isotropic by using high Zr concentrated PZT as underneath layer. Heterostructure films show a good ferromagnetic and ferroelectric coupling that lead to the large magnetoelectricity of 287mV/cmOe.
