Transverse and longitudinal magnetoelectric effect in multilayer Li0.058(Na0.535K0.48)0.942NbO3/Co0.6Zn0.4Fe1.7Mn0.3O4 bulk composites

We use the tape-casting technique to prepare multilayer magnetoelectric composites of Li0.058(Na0.535K0.48)0.942NbO3/Co0.6Zn0.4Fe1.7Mn0.3O4 (LKNN/CZFM). Scanning electron microscopy and energy-dispersive x-ray microanalysis indicate that the LKNN and CZFM phases coexist in these composites. The dielectric constant, piezoelectric constant, and ferroelectric properties of the multilayer composites deteriorate with increasing thickness tC of the CZFM layer. The maximum saturation polarization is 36.5 μC/cm2, and the maximum piezoelectric coefficient d33 is 205 pC/N. In addition, the maximum magnetoelectric coefficient is 322.3 mV cm−1 Oe−1.
