Abstract

We report the microstructure, dielectric, ferroelectric and magnetoelectric properties of Ba0.85Ca0.15Zr0.10Ti0.90O3/La0.67Ca0.33MnO3 (BCZT/LCMO) laminated composite prepared by Plasma Activated Sintering. A perfect bonding BCZT/LCMO interface without structural defects was demonstrated by SEM and TEM analysis. The remnant polarization, coercive electric field and ME coefficient of the composite were 10.1μC/cm2, 1.97kV/cm and 2.65mV/cm·Oe, respectively. Enhanced dielectric properties (Room-temperature εr=7217, εm=25,097, at 1kHz) were achieved for the laminated composite, as explained by the contribution of ferromagnetic LCMO and Maxwell-Wagner model.
