Abstract
Fe-doped BaTiO3 has been synthesized with sol-gel technique. Its transformation point of ferroelectric to paraelectric and the latent heat of the transformation were observed at 103.27 °C and 169.9 J/mol, respectively. They are a little less than those for pure BaTiO3. Bonded layered composites Tb1−xDyxFe2−y/BaTi0.99Fe0.01O3 have been fabricated. Their magnetoelectric (ME) effect has been investigated. The transverse ME voltage coefficient for the bilayer Tb1−xDyxFe2−y–BaTi0.99Fe0.01O3 and the trilayer Tb1−xDyxFe2−y–BaTi0.99Fe0.01O3–Tb1−xDyxFe2−y can reach 578 (mv Oe−1 cm−1) and 2100 (mv Oe−1 cm−1), respectively, under a bias magnetic field of 350 Oe at room temperature. Those are about 50% larger than those for the bilayer and trilayer composed by pure BaTiO3. It suggests that the doped BaTiO3 can be a new choice of piezoelectrics to compose ME composites.
