Abstract
Owing to the excellent conversion properties between magnetic and electric properties, magnetoelectric composites have been widely used in devices. With the growing concerns about the environment, developing environmentally friendly lead-free magnetoelectric composites with high performance are very important. Here, (1-x)0.82Ba(Ti0.89Sn0.11)O3-0.18(Ba0.7Ca0.3)TiO3-xCoFe2O4 [(1-x)BTS-BCT-xCFO] magnetoelectric composites are synthesized by solid-state method, and the effect of CFO on the microstructure and magnetoelectric properties is systematically studied. The perovskite type piezoelectric phase and spinel structured piezomagnetic phase in diffraction patterns are independent of each other. Due to the inhibiting effect of CFO on grain size for BTS-BCT, the grain size of magnetoelectric composites is dominated by CFO. The electric properties deteriorate, and magnetic properties increase with increasing CFO. Meanwhile, the optimal ME coefficients (αE31∼8.12 mV/cm∙Oe and αE33∼7.84 mV/cm∙Oe) are obtained in the (1-x)BTS-BCT-xCFO with x = 0.20, which are superior or comparable to that of some lead-based and lead-free magnetoelectric composites. Therefore, (1-x)BTS-BCT-xCFO material systems have a promising prospect in application.
