用溶胶-凝胶法制备了Fe掺杂BaTiO3粉体，在1350℃下烧结成圆片状多晶样品，并与Tb1-xDyxFe2-y胶合成磁电(ME)双层膜或三层膜.实验分析表明Fe：BaTiO3依然是四方相钙钛矿结构，但是居里温度及相变潜热均略低于纯净BaTiO3.研究了Tb1-xDyxFe2-y-Fe∶BaTiO3双层膜和Tb1-xDyxFe2-y-Fe∶BaTiO3-Tb1-xDyxFe2-y三层膜的ME效应.在2.8×104A/m的磁场下，两者的横向ME电压系数均达其峰值，分别为6.225和26.25mV·(A·m-1)-1·cm-1.并且，用掺杂BaTiO3制备的双层膜和三层膜的横向ME电压系数均为相同条件下用纯净BaTiO3制备的双层膜和三层膜的横向ME电压系数的1.5倍.另外由于不含铅，锆等有害物质，符合环保要求，因此采用掺杂BaTiO3制备的磁电效应器件具有深入研究和应用价值.Fe-doped BaTiO3 has been synthesized with sol-gel technique. The doped perovskite was found to have tetragonal structure. The transformation point of ferroelectric to paraelectric and the latent heat of the transformation were observed to be a little less than those for pure BaTiO3. Layered composites Tb1-xDyxFe2-y/Fe∶BaTiO3 have been fabricated. Their mgnetoelectric (ME) effect has been investigated. The transverse ME voltage coefficient for the bilayer Tb1-xDyxFe2-y-Fe∶BaTiO3 and the trilayer Tb1-xDyxFe2-y-Fe∶BaTiO3-Tb1-xDyxFe2-y can reach 6.225 adn 26.25mV·(A·m-1)-1·cm-1，respectively，under a bias magnetic field of 2.8×104A/m at room temperature，which are about 50% larger than those for the bilayer and trilayer composed of pure BaTiO3.
