Influence of residual stress on magnetoelectric coupling of bilayered CoFe2O4/PMN–PT thin films
Abstract
Multiferroic CoFe2O4/0.68Pb(Mg1/3Nb2/3)O3–0.32PbTiO3 (CFO/PMN–PT) bilayered thin films with different CFO layer thicknesses were prepared on Pt/Ti/SiO2/Si substrates using the sol–gel technique. The bottom PMN–PT layer exhibited a highly (111) preferred orientation as conformed by a bidimensional (2D) planar
