Transverse and longitudinal magnetoelectric effect in multilayer Li_(0.58)(Na_(0.535)K_(0.48))_(0.942)NbO_3/Co_(0.6)Zn_(0.4)Fe_(1.7)Mn_(0.3)O_4 bulk composites

摘要

We use the tape-casting technique to prepare multilayer magnetoelectric composites of Li-0.058(Na0.535K0.48)(0.942)NbO3/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 t(C) of the CZFM layer. The maximum saturation polarization is 36.5 mu C/cm(2), and the maximum piezoelectric coefficient d(33) is 205 pC/N. In addition, the maximum magnetoelectric coefficient is 322.3 mV cm(-1) Oe(-1).
