AbstractAbstract
[en] Thin-film heterostructures of Bi4Ti3O12/Bi2Sr2CuO6+x and Bi4Ti3O12/YBCO were grown on single crystals of SrTiO3, LaAlO3, and MgAl2O4 by pulsed laser deposition. X-ray diffraction studies show the presence of the c-axis orientation only, while Rutherford backscattering experiments show the composition to be close to the Bi4Ti3O12 stoichiometry. The films are ferroelectric and exhibit a symmetric hysteresis loop. The remnant polarization was 1.0 μC/cm2, while the coercive field was 2.0 x 105 V/cm. These films look promising for the fabrication of lattice-matched, epitaxial ferroelectric film/electrode heterostructures for memory applications
