    Direct measurement of magnetoelectric exchange in self-assembled epitaxial BiFeO3-CoFe2O4 nanocomposite thin films
    Yan, Li; Xing, Zengping; Wang, Z. G.; Wang, T.; Lei, G. Y.; Li, Jiefang; Viehland, Dwight D. (AIP Publishing, 2009-05-01)
    We report the direct measurement of a magnetoelectric (ME) exchange between magnetostrictive CoFe2O4 nanopillars in a piezoelectric BiFeO3 matrix for single-layer nanocomposite epitaxial thin films grown on (001) SrTiO3 substrates with SrRuO3 bottom electrodes. The ME coefficient was measured by a magnetic cantilever method and had a maximum value of similar to 20 mV/cm Oe. The films possessed saturation polarization (60 mu C/cm(2)) and magnetization (410 emu/cc) properties equivalent to bulk values, with typical hysteresis loops.
