摘要/Abstract

摘要： 采用溶胶凝胶法制备了Cr掺杂BaTiO₃陶瓷片.X射线衍射显示Cr掺杂BaTiO₃依然为四方相钙钛矿结构.差热分析显示，Cr掺杂BaTiO₃的居里温度及相变潜热均比纯净BaTiO₃ 的同类参量略低.将所得BaTi_0.99Cr_0.01O_3-δ陶瓷片与Tb_1-xDy_xFe_2-y粘结成磁电双层及三层复合结构材料.研究了双层Tb_1-xDy_xFe_2-y-BaTi_0.99Cr_0.01O_3-δ和三层Tb_1-xDy_xFe_2-y-BaTi_0.99Cr_0.01O_3-δ-Tb_1-xDy_xFe_2-y复合材料的磁电效应.在28 kA/m 的磁场下，两者的横向ME电压系数均达其峰值，为732.5和2753mV/A.该两数值分别是采用BaTiO₃制备的同类双层及三层复合结构的同类数值的1.54及1.56倍.由于掺杂钛酸钡不含铅、锆等有害物质，因此采用掺杂BaTiO₃替代锆钛酸铅做为“绿色”压电材料制备磁电效应器件具有研究和应用价值.

Abstract:

Chromiun doped BaTiO₃ was synthesized with sol-gel technique. The Cr-doped BaTiO₃ was still in the structure of tetragonal perovskite by X-ray diffraction, and its transformation point of ferroelectric to paraelectric as well as the latent heat of the transformation were observed a little less than those of pure BaTiO₃, respectively, by the tests of differential scanning calorimetry. Layered composites Tb_1-xDy_xFe_2-y and BaTi_1-zCr_zO_3-δ were fabricated by bonding the discs of the doped BaTiO₃ and rare earth alloy Tb_1-xDy_xFe_2-y. The magnetoelectric (ME) effect of the layered samples was investigated. The transverse ME voltage coefficient for the bilayer Tb_1-xDy_xFe_2-y-BaTi_1-zCr_zO_3-δ and the trilayer Tb_1-xDy_xFe_2-y-BaTi_1-zCr_zO_3-δ-Tb_1-xDy_xFe_2-y reach 732.5 and 2753mV/A, respectively, under a bias magnetic field 28kA/m at room temperature, which are about 54% and 56% larger than those for the bilayer and trilayer composed by pure BaTiO₃, respectively. Since Cr-doped BaTiO₃ does not contain injurants, such as lead and zirconium, it can replace lead zirconium titanite as a “green” piezoelectric material for ME composites.

Key words: doped BaTiO₃, green piezoelectrics, magnetostrictive material, magnetoelectric effect
