Structure and Electrical Properties of PbTiO3-CoFe2O4 Magnetoelectric Composites
摘要
Abstract
PbTiO3-CoFe2O4 magnetoelectric composites were prepared by a conventional solid-state reaction method with different volume fraction.X-ray diffraction and scanning electronic microscopy were used to analyzed and characterization the samples.The ferroelectric and magnetic properties of PbTiO3-CoFe2O4 magnetoelectric composites were measured.The results showed that the PbTiO3-CoFe2O4 composites were 0-3 type and exhibited ferroelectric phase and ferromagnetic phase coexisting.The composites sintered at 1 100 ℃ appeared the best phase structure.The magnetic property changed regularly with the test frequency, but the dielectric permittivity showed the anomalies, which was attributed to constraints and dilutions from the ferromagnetic phase and the element diffusion.关键词
