Probing the dielectric, piezoelectric and magnetic behavior of CoFe(2)O(4)/BNT-BT(0.08) composite thin film fabricated by sol-gel and spin-coating methods

We investigated in this paper a novel bilayer composite obtained by sol-gel and spin coating of the ferroelectric 0.92Na(0.5)Bi(0.5)TiO(3)–0.08BaTiO(3) (abbreviated as BNT-BT(0.08)) and ferromagnetic CoFe(2)O(4) phases, for miniature low-frequency magnetic sensors and piezoelectric sensors. This het...

description We investigated in this paper a novel bilayer composite obtained by sol-gel and spin coating of the ferroelectric 0.92Na(0.5)Bi(0.5)TiO(3)–0.08BaTiO(3) (abbreviated as BNT-BT(0.08)) and ferromagnetic CoFe(2)O(4) phases, for miniature low-frequency magnetic sensors and piezoelectric sensors. This heterostructure, deposited on Si-Pt substrate (Si-Pt/CoFe(2)O(4)/BNT-BT(0.08)), was characterized using selected method such as: X-ray diffraction, dielectric spectroscopy, piezoelectric force microscopy, SQUID magnetometry, atomic force microscopy/magnetic force microscopy, and advanced methods of transmission electron microscopy. CoFe(2)O(4)/BNT-BT(0.08) ferromagnetic–piezoelectric thin films show good magnetization, dielectric constant and piezoelectric response. The results of analyses and measurements reveal that this heterostructure can have applications in high-performance magnetoelectric devices at room temperature.
